New wholesale price indicates that apple is probably paying more for these tracks. However, it might be five cents, and apple sees room for profit. We'll have a better idea when we see the competition's prices.
Five cents would be a lot of Apple's profit margin on songs. Literally.
I am part of an indie band with a CD on iTunes (the Priestie Boyz'
Lost in Ecstasy), and, of every song sold, we get $0.63. And we go through an online distributor, CDBaby, which also takes a cut from what Apple gives.
So, from our $0.99 song (which still has DRM), about $0.70 goes to CDBaby (of which we get $0.63). That leaves Apple with $0.30/song. And Apple has to pay for: servers, hosting, bandwidth, web design, iTunes developer team, marketing, and credit card processing with that $0.30.
If EMI is charging $0.05 more per song, that means Apple has only $0.25 to pay all their bills. And with twice the file size (256 kbps rather than 128), the bandwidth/hosting/storage fees will, assumedly, double)...
Therefore I find it justifiable for Apple to raise the price (I thought it was inevitable from the beginning... $0.99 couldn't last forever).
