Seger is from here in Michigan, and people here just loooooooooooooooove him. Go to a show here and you're almost 100% guaranteed to hear it. I like him, but I don't love him (I'm from Massachusetts and the Live Bullet album was out before I was born).
Same with Kid Rock -- people here go bat$h!t over all his songs because he's from Michigan. I don't like his music at all, but "All Summer Long" references this area and he came here about 6 weeks ago to shoot his most recent video, so I can't knock him too much.
