A positive side of threads like this is they remind me of artists I need to go back and listen to. I love the Bangles' cover of "Hazy Shade of Winter", was playing along to it on guitar last night.
Went back and listened to the "Different Light" album this morning, great stuff, I like a lot of stuff they wrote themselves, but hey, when you've got someone like Prince contributing a song, that works too

That's part of why I think they're musically legit in my mind...they wrote their own stuff, but on some of the big singles with the outside writers, they still had their own sound.
I did NOT realize that Michael Steele was a founding member of the Runaways, leaving just before the first album. But that was the LA rock band scene back then in the late 70's/early 80's, musicians were in and out of each others bands all the time prior to getting signed and their breakthrough albums out.
While we all have our personal tastes and artists we're passionate about, being a hardcore musician myself I feel like music is not a contest. It should be an escape from the stresses of life, and enjoyment at it's purest. It's fun to debate artists' musical merits and historical importance and all that for sure, but if music personally means a lot to someone, that's all that matters at the end of the day.
