Pre-recorded downloads or streaming
There are many sites other than YouTube, SoundCloud or Facebook where you could consider posting your music: be aware that they may not have licensing agreements in place. You should therefore always check the terms of the hosting site with regard to copyright clearance or infringement before uploading.
Livestreaming
There are currently no licensing arrangements in place with Zoom, Twitter, Periscope or Twitch (although negotiations are ongoing with someof these companies). Therefore, make sure you follow the terms of use and copyright requirements of each respective platform and will most likely need a Small Online Live Concert Licence (see below).
