Similar to the 'Add to Playlist' option in the song menu, create an 'Add to Station' option where the song would be added as a new seed/variety for the station.
This has been needed for so many years. So many songs that come up may not fit the existing station yet are perfect for a different station and I'm bewildered as to why Pandora hasn't yet allowed us to seed our other stations, that would make the whole thing more accurate and useful for everyone.
You know, I would swear that they had this years ago (2011?) where you could add variety by adding another song. I remember being able to do this back in college. A handful of years back I went to do this again and realized that it was gone. I check back every so often to see if there's a new option.
This would also be really useful for helping a station to zero in on what you're looking for. Far too often I'll start a station with a song that I love but no amount of feedback will turn it into a station that I'd listen to. It always feels like a frustrating waste of time. 😓
