Just remember that there are other issues besides price. There has to be a sufficient warehouse of music, the quality must be high (not likely to happen), and what we're able to do with that music is very important. If I am not able to do what I want with it, the service is useless.
But above all, I'm with Bitt. I want my CD.

I happen to agree with this statement. For me to pay $1.00 per song or $10.00 per album, I was a lossless encoding (ie FLAC) with no DRM on it what so ever. If I don't get that, I'll spend the extra 3.99-5.99 plus tax and get a CD which I can do whatever I want with.
