Almost immediately, you'll notice that Andy has gone with a much more synth-laden production rather than his signature piano rock style. This isn't to say he hasn't completely forgotten his roots, as there are still glimpses of his piano throughout the song.
He demonstrates a great use of space on this track, especially with the chorus -- which is choppy as all hell, but incredibly original and well thought through. The verses swing off the chorus really well and have a sort of hip-hop feel to them, which gives this track a particularly nice ebb and flow.
Hope this fills you up with as much as happiness as it did for me!
