SynchTunes

I started a music room on SynchTube. It'll be playing a playlist repeatedly that'll be changed and tweaked regularly.

It'll be a mixture of rock, pop, and jazzy music.

SynchTube lets you chat and watch videos in sync with other people. A great tool. Especially good if you want to get real time reaction to your videos as you can add to the playlists of most rooms.
