By now you've probably had the opportunity to play around with the new iTunes Visualizer in iTunes 8. It's pretty cool, eh? Just like the previous visualizer, you can control this one with a few, simple key strokes. By pressing "?" while the visualizer is running, you are presented with a list of keys that customize the visualizer.

• ? - Shows/hides the help screen
• M - Changes the mode
• P - Changes the color palette
  
• I - Displays the track information for the currently playing song
• C - Toggles "auto-cycle" (which is turned on by default)
• F - Toggles the "freeze mode"
• N - Shows/hides the "smoke" in the background
  
• L - Toggles camera lock

Know of any more cool key combos for iTunes visualizers? Be sure to tell us in the comments!

Thanks to Luke and others for the tip!

The feature of iTunes 8 that Apple wants to you notice is called "Genius." Basically, it generates playlists, either from your songs or the iTunes Store, based upon a track selected from your library. In this post, we'll look at creating and saving a Genius playlist on your Mac.

First, select the target track in your library. I wanted to generate a playlist for work, so I selected a mellow track by Band of Horses. Next, click the Genius button (with the icon) in the lower right-hand corner of the iTunes window.

Presto! Your playlist is created. But there's still room for tweaking. At the top of the window, you'll see the track upon which your new playlist is based. Next to that, a drop-down menu lets you select the number of songs to include. Choose from 25, 50, 75 or 100.

Finally, you can exclude an individual song by deselecting the gray checkbox next to its title. When you're happy with the result, click "Save Playlist" in the upper right-hand corner.

Your new playlist will now appear with the others, named for the original target song.

In the iTunes 8 new features listing, a couple of tweaks may have been overlooked. Podcast subscribers have long yearned for more granular control over downloading and retention in iTunes -- "keep three episodes" might be great for Wait Wait, Don't Tell Me or Mac OS Ken, but what about Coverville or You Look Nice Today? You'd surely want to keep those & other awesome 'casts in perpetuity, and there are some podcasts that are so large you want to cull them after one download.

Now, iTunes 8 lets you apply retention policies on a podcast-by-podcast basis. Select the podcast in the list and click the "Settings" button at the bottom of the window, then UNcheck the "Use Default Settings" box to enable custom prefs for that particular show. Dee-lightful! Unfortunately, podcast-to-iPod sync settings are still one for all and all for one, but this is a step in the right direction.

Update: Comments below (and a visit to the Wayback Machine) have confirmed that the territorial clause in the iTunes store TOS is not a new addition with v8, but has in fact been in place for quite some time. It's interesting that it only came up as a topic of discussion now -- perhaps because everyone was forced to reaccept the TOS with the new version, and read it a bit more carefully? It's also looking like the clause was displayed front and center on the new TOS acceptance screen; this degree of prominence seems to be new, and probably attracted attention to the pre-existing restriction. In any case, our apologies for the error.

Speaking of minor changes that might have major implications, a number of readers have expressed concern about something that Robert originally pointed out in his rundown of iTunes 8: that the iTunes store terms of service (long a source of controversy in Europe) now include have long included a clause restricting use to the geographic area where the user's account is established. In the US the rule reads:

10. Territory. The Service is available only in the United States. You agree not to use or attempt to use the Service from outside of the available territory, and that Apple may use technologies to verify your compliance.

There are several classes of users who might run afoul of this restriction: travelers who shop in their home stores while venturing abroad, for example, would technically be in violation... but our suspicion is that these casual, intermittent border-busters are not what Rule 10 is about. Instead, any enforcement of this restriction is likely to be aimed at users who live in one country and establish an iTunes store account in another -- allowing them to buy TV shows or movies that may not be available yet (or ever) in their localities.

Certainly the content providers who sell their wares through iTunes may choose not to sell their programs to a particular region at a particular time; that's their prerogative. It seems somewhat myopic, however, to think that enforcing restrictions by geography in the iTunes store will have any effect other than to drive revenue and customers from the quasi-legal market firmly into the rip-and-download underground.

Now that today's press event is over, we can review our earlier predictions and see how well we did.

Just half an hour before it started, I guessed that Steve would reveal "...a revamped nano line, with greater storage, a new design and UI." The design and UI are certainly new, and the storage capacities have changed to 8GB and 16GB.

I also predicted a price drop on the iPod touch (got that one), iTunes 8 (one more) and HD content (trifecta!). Not bad.

What I missed: All of the nifty new features on the touch, new accessories and Steve's brown shirt.

Last week, Erica predicted "...a revamped nano with a longer silhouette," and was right on target. She also predicted a re-tooling of the Nike+ kit, and was half right on that one. It's built into the iPod touch now, but the functionality is the same.

Many people thought we'd see a subscription-based "iTunes Unlimited" today, but it didn't happen. Finally, Erica predicted iPhone 2.1 and iTunes 8.0. All in all, we did pretty well.

Thanks for playing along and let us know if you buy any of Apple's shiny new toys!

At Apple's "Let's Rock" event today, they unveiled the newest version of iTunes: version 8. The rumors were mostly right: iTunes 8 includes a new feature called "Genius" that allows you to "rediscover your iTunes music." Genius works by matching music with your listening tastes. The Genius interface looks similar to iPhoto and works similar to Pandora (or Last.fm).

iTunes 8 will be a free update later today, and we'll have more about it then. Stay tuned to TUAW as we provide coverage of Apple's "Let's Rock" event.

On the heels of our earlier post about new features in iTunes 8 comes this post from video producer and designer Allan White, speculating that the new visualizer in iTunes might be Processing artist Robert Hodgin's amazing Magnetosphere, which was available up until a few months ago from The Barbarian Group (aka Robert's design company) as an iTunes plugin.

As Allan points out, there are two very strong pieces of evidence for this: 1) Allan emailed Robert, who told him Magnetosphere had been sold to a "third party", and 2) a twitter from Digg founder (and amateur Apple rumor mill) Kevin Rose on Sept. 2nd describing the new visualizer as "planet like objects wrapping around each other w/stars/light streams". As you can see in the image above, this sounds like a pretty apt description of Magnetosphere, which visualizes sound as particle explosions like supernovas. The Barbarian Group website's page for Magnetosphere says that "We've had a ton of interest in it, and we've got some exciting plans, but it's gonna take us a couple months to make it all happen."

Of course, nothing is confirmed, but it all points in the right direction. Personally, I'd love to see Magnetosphere on every iTunes user's screen, and not just because Robert is an amazing artist and also always gracious and helpful when I email him because my Processing particle system animations don't look as cool as his. The world just needs stuff this cool-looking everywhere.

(Thanks to Poopie for noticing that I'd accidentally added an "s" to "Hodgin"!)
