I assumed, I'm pretty sure all of them but "I Don't Know How But They Found Me" have below 500k listeners on spotify, so they're not "big". Kind of why I picked them, new stuff can inspire. That and the wildly different vibes and genres.
And Burn the Ballroom is my favorite band (i was in their top 0.001% of listeners last year i think?) , I'd suggest giving "Kiss me you animal", "Crazy", and "Story of the End" if you wanted to try out their stuff. Those are my favorites.
Oh, and if my bad music taste tickles your fancy at all, behold! My work playlist.
