99 cents is cheaper than buying a whole cd for two songs.
Exactly. But a lot of people seem to be missing that. I'd rather buy the hit songs on an album and then preview the rest with the 30 second clips, grabbing what else catches my ear. On many CDs these days, that'll total about three or four worthwhile songs. $3.98 later and I have the music I want legally. Normally I'd go down to my local Circuit City (ever Tuesday) and spend $13 for the same album and hate half of it.
It'll be interesting to see what happens once this service succeeds and people stop buying whole albums. I wonder if it will drastically change the music industry.
