Check out Bass Kleph. His old radio partner fRew has some free podcasts that you can download.
If you want to delve into the harder core drum and bass area check out Pendulum, Chase & Status, High Contrast, DJ Hype, DJ Hazard, Brookes Brothers, NuTone, Shy Fx.
Other artists to look out for are Freestylers, Breakfasataz, Stanton Warriors, DJ Icey, Cut n Run, Deekline, Deekline and Wizard, Keith Mackenzie, Dave London, DJ One (Dave London's bootleg name), Rogue Element, Ctrl-Z And Screwface, and a few others.
As for house, I like Vandalism, Dirty South, Klaas, Deadmau5, Chris Lake, Aquasky, Laidback Luke, and Tocadisco.
I used to DJ so these are the names that I am remembering off the top of my head.
