Streaming rules depend on the platform, the use, and the permissions that apply to each track. Some platforms allow specific permission-based uses or provide a program with its own approved catalog.
For example, the Twitch DJ Program has its own catalog and requirements. Downloading a track from Digital DJ Pool does not establish that the track is included in that catalog or covered for a stream.
Check the current rules for the platform you use and the Digital DJ Pool Terms. You may need permission or a license for your intended use. YouTube also explains its copyright and music-claim process.
