Last night I grabbed a bunch of audio files for country songs that contain the phrase "ice cold beer," then I edited them together so that all the "ice cold beer"s lined up amidst the cacophony of about 5 songs being played at the same time. I thought that would be funny but it just didn't sound as good as I thought it would. Maybe if each song faded in one by one... I dunno.
Hmm, maybe PeerTube? Looks like there's some instances that are specifically dedicated to music; here's a link to some search results on joinpeertube.org
