Picky used to be Pod+, but since WWDC (when this was filmed), the developer has changed the name.

The idea behind Picky is simple: a tool for quickly filtering through artists and songs by viewing them based on how many songs of theirs are on your iOS device. When Pod+ became Picky, the dev who created it (Charles Joseph) gave it a substantial UI facelift. The result is a simple tool for picky music listeners.

In this Origin Stories, we learn why Charles made Picky. As you can imagine, he wanted to tame his own music collection.
