On the word of mouth front: I started music group on various platforms; Play 3 Playlist Fridays

Basic premise is that on Fridays people share their own 3 song playlist of whatever genre, theme, etc that they care to. I'd say it has been moderately successful. 3 songs once a week is a low enough bar for contribution, but still high enough that people tend to put some actual thought into it.
