Custom mp3 upload
Youtube video - if there are ads on the videos, they will show!! Important to upload a video without monetization. Video suggestions will also show when the song stops playing.

Soundcloud - no ads but songs in this library are mostly indie productions. Not autoplaying here.
Medium size (allows viewers to understand where sound comes from and pause it):
