i trade 1 for 1 on cds. not from mp3 source, please. im not real picky about the media. as long as it plays and is not wobbly or scratched up. any major brand will do. i use memorex, tdk, fugi (whatever is on sale). i can trade through shn also. i have a personal password protected direct connect hub that i can turn on. i can give you a user name and password for that session. i'm also pretty nice about blanks and postage.
