Ah yes, Snail Mail, one of my secret pleasures. I first heard "Heat Wave" in 2019 at a coffee shop but the barista couldn't access the playlist to tell me who it was. I remembered enough of the lyrics to find it on YouTube when I got home. I was actually listening to the song you linked to as I was reading this thread, haha.
Earlier in the year a friend of mine tried to get me into Phoebe Bridgers but it didn't stick. Japanese Breakfast sounds pretty good, I'll check out more of their stuff.
I'll leave you with Soccer Mommy
. I think I like her style more than the music, but generally i find it more interesting than most of the girl rock out there.
