The Garbage cover, not half-bad. As for the Snow Patrol snippet, I'll save a final analysis for the final version. However, now that I remember it, they did the same thing with the INXS song New Sensation, basically taking out all the energy from it and singing it over a somber background.
Granted, INXS actually did something similar on their Original Sin album this year, but I don't think covering a song necessarily means you have to play it slower if it's a faster, catchier number. We'll see how this one turns out though.
