.WAV files, wot?
We suggest you upload a Lossless .WAV/.AIFF/.FLAC File as it allows us to create the highest quality MP3 format for your fans to download.
If we don't do this, then your fans could end up with all kinds of junk and that's not cool.
We add all the meta data and artwork to your mp3s too, which is ace.
We do allow you to upload 320kbps mp3 files if you want, but it's not recommended.
