MVGEN is a really cool site where you can upload your music and get a crazy music video for it. Check out this retro thing it made for my Game Boy track Crunch Beats (Extended Version)
Something called the Unepic Stoned High SID Collection has been recording over 50000 tunes made on the Commodore 64. Since I was very much a part of that scene from the mid 80s to early 90s, naturally all my tunes are included. I made a playlist with all of them for your chiptune enjoyment. I put what I consider to be my best tunes from back then at the top of the list.
