I responded:
According to your rules, people who also sing are not musicians. Because Thurston Moore and Kim Gordon were married, neither Thurston nor Kim are musicians on your list, if we apply the same rules to men.
The Beatles? A boy band. And they were all singers. The Rolling Stones? A boy band. Robert Plant? Not a musician.
Fleetwood Mac? They all did each other. Jimi Hendrix? A singer. Kurt Cobain? Singer. Dave Grohl? Singer. I did come up wit Mitch Mitchell, who did not sing backup in the Jimi Hendrix Experience.
Keith Richards cannot count as a musician because he's in an all-boy band.
Your rules are arbitrary, and since you seem to be the one who can decide whether or not a band or musician in well-known (and the criteria of being well-known is that you know who they are, which is absurd given that you have no idea who Liz Phair is).
And when your rules are applied equally: No boy bands, no mixed gender bands in which the male is a singer or has slept with another member of the band, etc) it doesn't work for you, either.
If you've no idea who Sonic Youth is, or the Yeah Yeah Yeahs, or Liz Phair, I would submit that you haven't read an issue of Rolling Stone or Spin in the last 20 years. This would make you not very familiar with rock and roll.
So you've purposely set up requirements that discount Patti Smith's guitar. These same requirements also knock Hendrix out. And Cobain. Go ahead. Give it a whirl. Give me your well-known male musician who is not a singer, in all boy band, or has slept with another member of the band.
David Bowie? Not a rock musician. Springsteen? Doesn't pass your test. In fact, the only thing keeping Clarence and Little Steven on the musician list is that Patty Scialfa in in the E Street band, making them NOT an all-boy band. Yay for Patti. Is she not well-known? She can't count as a musician, though, since Bruce.
Give me your list of well-known male musicians who are not in all boy bands, aren't singers, and don't sleep with any of the members of the bands they're in. You cannot count Billy Joel, Rage Against the Machine, or Soundgarden.
And then apply weirdly arbitrary rules to philosophers as well, since that's your analogy.
How about we don't count philosophers who are primarily professors and use apple computers?
If your point is that sometimes men bend backward to create weirdly arbitrary rules in order to discount the accomplishments of women (you can't count as a musician if you sing = you count count as a philosopher if you type your papers in Times New Roman?) then you've made an excellent point, and I agree.
