I’m planning on posting a music pack of decent songs and memes relatively soon. Nothing that big, but it might be about 40 songs. (I might release the many Ear Rapes I made as well.)
Currently however, I recommend digging through
Stick Man’s Music Pack, he has a lot of good loops.
If you’re looking for a variety of songs my
Mercury Meltdown Music Pack might be useful. It’s from an old PSP game with a really diverse and superb soundtrack that I highly recommend checking out. (It has 59 songs that are big in size. Please don’t use them all, as it will be a hefty download.)
