There are a couple different ways to answer this question. There's a yes, and a no involved. Back when I was around 12, I loved the whole pop sensation. Spice Girls, Britney, Christina, Backstreet Boys, the like. I also liked Blink 182, Sum 41, Simple Plan. (And to be perfectly honest, I was in love with the Waiting video when it premiered on TRL as well, but wasn't really sure who Green Day was. Just the song.) Then popular music changed, and I just... couldn't find anything I liked. I still liked the things I liked before, but it wasn't popular anymore, and I just... gave up on music in general.
Then around 2004, I loathed George Bush. I kept seeing this clip of a video between shows on MTV, and a band singing 'Don't want to be an American Idiot' and I just couldn't get it out of my head, and I was ecstatic to hear something that reflected what I'd felt. I was watching with my dad one day, and it came on, and I was like "THAT! That's the song I've been telling you about!" and he goes "...that's Green Day. I have one of their cds." It was Dookie. He gave it to me, I fell in love. I got American Idiot- I was in love. I continued to collect the albums, and they quickly became my favorite band.
They got me into alot more rock type music as well. But as far as changing my music taste, I don't think that they did. I think they simply expanded it, because I'll admit, I'm still a sucker for that 90's pop.
