So I have a Spotify list called "Top One Each" where I have to pick just one favo(u)rite song from an individual artist, which means I have to make some really, really difficult choices among bands I love (and go re-listen to their music), and then some easy choices from one-hit wonders, especially those bands from the 80s and 90s, and pop radio. I think I'm up to 250-some tunes now.
My latest 5 additions: "Eighties" by Killing Joke, "Mandinka" by Sinead O'Connor, "My Happy Ending" by Avril Lavigne, "Found Out About You" by Gin Blossoms and "Can't You Hear Me Knocking?" by the Stones.
I am struggling mightily trying to pick one song from Sleater-Kinney, who have produced at least six great records plus a couple of good ones, so I guess they're my obsession currently. I know they turn a lot of people off because of Corin Tucker's voice, but they are fantastic. It is not even arguable that they are the best band without a bass player in the history of rock. And Janet Weiss is an incredibly underrated drummer (or was, since she split).
