Both Green Day and (some) Red Hot Chili Peppers have appeared on Apple's iTunes Music Store.

While we don't normally report on band appearances on iTunes, both of these bands were previously reported as bands that were unwilling to agree to Apple's iTunes Music Store terms.

Specifically there were concerns about allowing the sale of individual songs off of albums -- rather then the album as a collective unit.

Admittedly, the Red Hot Chili Peppers' album is a Greatest Hits collection and may not represent a change in policy for the band. However, as more and more online music stores make their way into the market, bands may be pressured into participating in digital music distribution.
