Wanna delete songs?
Go into the songs list where the songs located
Usually in "BoXplorer"
Go in "Udata" or something.
Do not delete the file itself, if you do, it will freeze your ass.
Go into each file (each song) and delete the song data. Leave the file alone because the file itself doesn't take that much space. You can actually delete everything that way. Even the song when you first get into the game. Are we cool?
