According to analysts Forrester Research, the bottom has fallen out under Apple's iTunes store.

Apple doesn't release sales figures, but those clever analysts analyed credit card data and report that, since January, the monthly revenue for iTunes has fallen by 65%, with the average transaction size falling 17%.

That's bad news. But it gets worse. It's not just Apple whos sales are in the toilet. Nielsen Soundscan has has reported three consecutive quarters of flat or declining revenues for the digital downloading sector as a whole.

This is due, some experts think, to consumers not liking digital rights management on purchased music. I'm inclined to agree. Personally, I don't mind paying a buck a song, but I don't like the idea that I can only copy it a couple times. Not as a pirating thing, but because I have a couple MP3 players and sometimes like to burn CDs for myself... so I rarely buy tracks online.

How about you? Do you shop for music online? If not, why not?
