For me, since F.U.N came out with Some Nights, I've been obsessed. The first few lines even are such a pick me up and the melody is great! Save me San Francisco by Train. Another up-beat tune, but that's part of what picks me up! The song talks about his happy place. Then there's All The Same To Me by Anya Marina. This is a more chill song, jazzy. "Don't let 'em kill your song, so I keep on shuffling on and on, 'cause it's all the same to me'. Mhm yes. Just writing this post makes me happy. If you liked any of these or want any other ideas in any specific genre, send me a message! All the best etc.
