For sure, they offer a ton of free sounds. I'm digging your stuff too, especially dat low end.
I just uploaded the stems for the track if you're interested: https://www.dropbox.com/sh/8gd08ue3gndpsb5/TXs6mNtHM5
If you do something with them, let me know. I'd like to hear it.
Well, unfortunately, I think I only named 2 - Muse (which you already know) and Tame Impala (which is basically Kevin Parker's - the lead singer's project; he writes almost all of the stuff and records it alone too). I would gladly recommend similar artists to Tame Impala, but there's just none. If you want to actively look for new artists, I suggest this tool: http://www.gnoosic.com/
Have you tried plugging the cord from your UE speaker into the Headphones port on your Focusrite interface? They make cheap converters (I.e. https://www.amazon.com/dp/B005E2Y0KK/ref=cm_sw_r_cp_api_3Br0zbH9R5X63 )
