The Canadian Supreme court ruled on two copyright cases that affect music previews in iTunes and video game downloads. According to a report in Paid Content, the Court upheld the Copyright Board's decision that the 30- to 90-second audio previews in iTunes do not constitute a public performance and do not require a copyright payment to the music industry.

The Court also reversed a Copyright Board decision that a game download was a public performance of the music in the game and required a separate copyright payment. The Court chastised the music industry for trying to double-dip as game makers already pay fees to include the music in the game.
