Since I lost the music I used for the test demo on my old laptop, I am going on a binge to find music that I can use for the stages when 0.9.0 comes out. Here is a list of sites I have found.
Brawl Custom Music
Dwelling of Duels
Could you post links to similar sites I can use? If not, that's fine, but I will thank you if you can do this.
If you are wondering about said music I lost, I luckily have it on my iPod (with the exception of the Battlefield music), but you know how iPods and unsynced devices are.
