So, what are some common traits of the stuff you've liked? It would be easier to make suggestions based on clues. You say you like beats in hip hop, and riff-heavy metal can have the same effect, I'm gonna throw some sludge/stoner at you.
Unfortunately, they don't have anything from the album I'm looking for on Youtube, so I'm using a Grooveshark link to the song I'm look for. Hope that's cool.
Acid Bath - Tranquilized
And if you still don't get what a riff is, it's basically what a rhythm guitarist plays as opposed to lead guitar. It doesn't have to be, but in the context of what I'm giving you it's the repetitive riffs played throughout the song. They form the backbone of the song.
