well i use a Mac
i used to use Hotline, which is probably alot different than anything like Kazaa. servers require a membership, which you get by uploading requested abums, paypal or sometimes clicking on their banner. i'm really into underground indie rock, and there are alot of servers with hundreds and hundreds of albums to a server. corrupt files aren't an issue, and all music is sorted and high quality. most everything i download or upload for that matter was 192kbps.
