The production is laid back in the same that "Buzzkill" was (during the verses at least). The chorus gets off to a bombastic start with crashes surrounding call me, call me, call me's but that wears off after the first 7 seconds or so.
Bryan's performance is earnest and charming and is truly what makes the song memorable.
The story line is somewhat interesting and the creative title hook of baby you can crash my party anytime deserves credit, but my personal favorite part is this line: "Hell we can all go raise some hell on any other night". It gives some insight as too why the breakup (if that is indeed what the song is about) occurred in the first place. What I mean by that is he was partying instead of being with her and he sees the error in his ways. Or maybe I'm over analyzing it.
Either way, it is quite an enjoyable tune.
