For me, deadmau5 is really hit or miss. A lot of them are pretty similar, but a few stand out, especially "Careless". The lyrics (which come 3 minutes in xD) are pretty profound and I like the piano aspect. It's autotuned to hell but I think in this example it makes it feel "artificial" in a good way.
Also I listen to his more ambient stuff while reading or drawing.
