Will isn't old enough yet to be able to recommend bands to me, but he does seem to like the same ones I do. I guess he probably would no matter what I liked, but he really has taken a shine to Green Day and asks to hear specific songs when we're in the car. Sometimes we listen to the radio, and I often have it tuned to a new rock station - that's the only way I find out about new bands like the Arctic Monkeys - I don't watch MTV or any of those anymore (not that they show music videos anymore, anyway). He still seems to like the same stuff I do, even if he doesn't know I like it when we're listening to it.
Even my fuddy-duddy husband likes Green Day's "Warning" CD. I call it a kinder, gentler "American Idiot." There's a common thread that links all those songs together, too - it's kind of their precursor to the ultimate concept rock album.
Katherine, I will most definitely check out those two Soul Asylum CDs. I'd love to hear "Runaway Train" again - they almost never play that on the radio anymore.
