I want to make the leap to the iTunes Music Store, but the quality has always held me back. The convenience is astounding, but you're paying for it! You can't switch formats, bitrates or anything. I really like ripping my tracks AAC@256kbps VBR. On the other hand, you get album covers, instant access... And also, do you think the iTMS will offer "hi-fi" tracks? Will the 128kbps standard ever be raised? If so, do you get the option to upgrade your tracks, or do you have to buy them again? Any thoughts?
