Okay, so I followed a guide to converting the DS music files into MP3. And the first thing I tried extracting it the music from EBA (sadly, I have to admit some of the covers were good). Unfortunately, it turns out it's not 1 music file but rather, to save space, several files which consist of first part of song then chorus then second part of song then chorus again. In short, is there a good MP3 editting program that just lets me join the songs together?
