Mine recently, currently is, "I don't want to fight no more" --Alabama Shakes. Because, it gets me right between the sticks, for some reason... dunno why, just luv 'it, them, her
"Mainstream"... who knows *how* (?) to define it, but you get my drift!, I hope?
Sometimes the more one explains, the less clear they become -- What I mean is... I can't know the song your local favorite bar-band in your town has just released. I guess you could link to it, but, was just thinking like, well, --stuff someone could possibly know without flying in to see for their self
(And no, not from 5090/FAWM that already has a thread!)
However, maybe the more obscure is warranted? I dunno... Alabama Shakes was a garage band that went from covers, to mix, to just their stuff. They get featured on late night "music" shows, --"Austin City Limits", etc. other... so, imo, they are beyond "garage band" status at this point.
-- Oh, well...
