I have an mp3 search and download site, which is against their TOS. If i disabled the download option and only allowed playlists and streaming music, do you think this would be ok?
for the video sites is the rule that you have posted You may stream videos from youtube but cannot offer download for them For music sites im not sure
Unless you have permission to stream the music, it would be copyright infringement and against the adsense tos. Anytime you are in doubt, set up a test page and email adsense telling them the page isn't public but wanted to know if it complies with their tos. They usually respond within a day. That way you have a written response if issues come up later.
if it a music sharing site, then most likely people will be searching for random musics and download them which would make it a violation of copywrite. unless you have permission to distribute those musics, i would not suggest putting adsense on such a site
