Suggestions Welcome

So I was driving from Cleveland to Chicago a couple of weeks ago, and it's a fairly long drive, so I decided to listen to my entire Dar Williams discography in chronological order. So I did that, and after 5.5 hours of Dar, I decided I wanted something with men's voices instead of women's voices. So I went rifling through my CDs - all of which were in the car with me - and I couldn't find anything. I'd listened to one Jars of Clay album and both my U2 albums on the way to Cleveland. I had a lot of Beatles and some Simon and Garfunkel, but I was in the mood for something more recent than that. I have one CD with some One of the Girls and some Great Big Sea, but I'd listened to that recently too....

I'd known for a long time that I listen to a lot of women's music, but I didn't realize how few CDs by men I had. So I'm on a mission to start evening out that ratio a little. I went through my iTunes, and I realized that about a quarter of my iTunes library is actually music by men, and that doesn't count all the musical theater stuff I have that's sung by men. It's just not on CDs - partly because a lot of it is downloaded singles, rather than albums. So I'm going to burn myself some of that stuff before I drive home next time, and/or get a working iTrip.

Still, I've been looking for some new music anyway, so I'm open to suggestions. I already wanted to get more U2, so that's covered, but what else should I be listening to? I tend to listen to a lot of women singer-songwriters, but I don't always respond as well to men in that genre. I'm probably more interested in pop/rock/alternative kinds of things - I like U2, I used to like BNL and Blink182 a lot in the 90s, I like Stephen Kellogg, I like both Guster and John Mayer, to the dismay of some of their fans. I'm not a big fan of Bruce Springsteen or John Mellencamp. Anyway, I'm listening more to the radio for ideas too (especially since I'm also interested in getting more current pop music into my collection), but I'd welcome suggestions from my readership.
