Funny, I just installed the iBooks app today and expected all the prices to be $.99.
Why would you expect that though? At iTunes, you don't expect to get the new $MUSICAN album for 99 cents, do you? Individual songs, sure, but not the album. A song is not a novel, it's a chapter.
When did writers become the absolute bottom of society when it comes to value of their work? A musician gets $10 or $12 for an album (assuming it's actually worth buying all the songs from it),
Actually on the typical album the musician gets ZERO. First, the music label contract makes the recording a 'work for hire' of the record company so they own it, not the musician. Now the record company pays the musician an advance. The album is charged for all costs in its production. There is supposedly a percentage of the profit that comes back after it makes the costs. If it doesn't make back the advance and all costs to produce the album, the musican gets nothing from it. Also, the advance is against all royalties the performer's work generates. So it means if a performer gets $10,000 as an advance, the record costs $150,000 to produce, it sells 20,000 copies at $20 of which, say, half goes to the distributor and retail seller and the musician is supposed to get a 10% royalty, it means the record company made $200,000 of the $400,000 the record made. From that they take the $160,000 and now the record only made $40,000. 10% of that is $4,000 so the performer still owes the record company $6,000 since his advance wasn't recouped!
So the musician basically becomes a chattel slave of the record company. Most of them only make money from performing, not from their records. You either have to have the will to walk away unless you get a good contract or be a big star before you make any money. Or start your own record label. A&M Records, for example, stands for "(Herb) Albert and (Chuck) Mangione", who probably got sick of being screwed over by other record companies (and decided to do some screwing over! :) .)
