And Rammstein, by the way, isn't just guitar riffs; it's a band and their music. Guitarists often suffer from only hearing the guitar and nothing else in the music.
I agree, there's also electronic music there, and that's also metal (but not heavy metal, of course).
Personally, I listen to metal (rock) because I like the sound of the guitar, but pop music is also diverse, like pop-rock, etc.
P.S. It's a funny topic to discuss pop music; you just don't need to listen to it and forget about it.
