Yeah, I like it and it grows on me. But it isn't blowing me away either. It sounds like a decent upbeat album track rather than a punchy lead single.
However, it has more going on than in The Blackout. Better melody and chorus, more hooks, less one-dimensional and less...I don't know...clunky perhaps.
For me, though, Little Things is the best of the three new tunes I've heard so far.
