I pretty much feel the same way that you do. I was a big fan at first and now I could care less if I ever hear another song of theirs. It is a shame that bands often lose their touch within such a short time.
I still like their music, I dont listen to it as pften as I did when i was younger, but I still enjoy it. Even though their songs sound the same, they all sounds very different to other peoples songs. They are very unique.
