The simple answer is most electronic and orchestral, but I get kind of picky. The songs that really grab me are in genres like Nu Jack Swing

Those Euro 90s dance songs:
(Yeah I know that's Sonic, but that's the only one I could think of. I know it's cheesy, but I like the way these types of songs sound.
Jungle DnB:
Film Noir Jazz:
(These are just so mellow. This + Rainymood = perfect)
I normally listen to instrumentals and video game music though.
However, I hate to say "video game music" because those are still in genres. I feel that songs in games (more often than not) have a bit more character. That's not to insult other songs.
I like a lot of songs with interesting chord progressions as well regardless of genre.
Oh, and I also like listening to whatever you'd call this.
