Dunno why dub is catching strays, there's great groovy dub. Check out ‘Stepping to Kebra Ethiopia Sound’, ‘Trojan Dub Massive Volume One’ and Volume Two. Or, for more melodic dub, try Zenzile.

Hiphop by itself is meh, but instrumental hiphop is another thing. Particularly, Ninja Tune released lots of good music: e.g. Wagon Christ.
