Schlager...
Schlager is a genre of music half-way between modern rock and traditional folk music.
--Simple melodies deliberately designed to get stuck in your head. It's typically (although not always) sung by an attractive woman and often sickly sweet. (Enough to make your teeth fall out.)
English speakers might be familiar with ABBA, Aqua and A-Ha, which are all technically schlager, although not the purest examples of it.
It's not that I don't like other, more serious forms of music. I do.

Here's a good example: (Not that I've ever listened to it - LOL)
