Can you help suggest some music to add to my Spotify playlist?

I have a playlist that I need to diversify more! It’s mostly uplifting, upbeat stuff. I’ve got plenty of Dave Matthews, 311, Grateful Dead, Tom Petty and similar stuff. I also like Fair to Midland, Cage the Elephant, Fun., Bob Marley, Steve Miller Band and have some tracks from those artists too.

Anyone got some good suggestions?

(EDIT: Feel free to suggest your own playlists as well and I can search for them)
