I was wondering... when the FULL album comes out (in may i believe) then do i have to by the song again? cos i am planning on buying the full album, but does that require me to buy the song again?What happens when full album comes out?
when the album comes out, there's a "finish my album" option, and you get the album but like 50 cents cheaper.What happens when full album comes out?
From the last time I bought something on iTunes the cost of songs you bought from an album are subtracted. I don't know if this applies to songs released as official singles separately, I would think it does. But iTunes are greedy ***** so you never know.What happens when full album comes out?
