Yay I'M glad this uploaded successfully. I was worried last night when I tried to upload my song, that it could fail.
As for MP3s I guess you can always use WAVs, then audacity to convert to mp3. Avoid Nero, though, because some of its MP3s won,t play fine in some players.
That reminds me... I have another song somewhere I made in MTVMG3. It's recorded on a VHS tape, I believe, though.
