They're pretty good and I think I'll listen to more of them.

Here's a musician secret: Most musicians don't like just one genre of music. There may be one that they prefer to play, but we look for inspiration from as many souces as possible. When I started playing bass many moons ago (okay, decades ago) I was a huge punk-alternative-gothic rock fan. But while learning bass I was introduced to the blues, jazz, and funk. My musical "horizon" spread and hasn't diminshed since. (There are some genres that I don't care for, but there are songs in those genres that I'll tap my foot to and/or try to learn at some point.)

Just think of it as part of your evolution as a musician. And I don't think deathcore music would be very useful for serenading someone, unless that's the type of person you're looking for.

Have fun and happy practicing.
