Tidal symbol?

Help me out- what does the symbol circled in red mean on the Tidal app interface?

 

[Spin Doctor]

I think that's the "start radio" button? ie play me more songs like this one?

 

[smistry007]

Sort of a “like” button?

It starts a radio station based on the song currently playing (ie a playlist of similar songs)
