I agree completely. When I first bought the album Every Time We Touch by Cascada, I thought it was the best album ever. But I listened to it so much that I got sick of it, and now I can't even listen to half of a single song by her anymore without getting bored. I know she has released several albums since then, but none of them have even come close to being as good as Every Time We Touch. I went through the exact same thing with Aqua's album Aquarium, and to a lesser extent, Aquarius as well.
The only bands I listened to as a teenager that I still enjoy are Evanescence, Flogging Molly, and The Corrs, and that's because I made sure not to listen to them too often.
