I really like the guitar accompaniment, it sounds very natural and has a nice and chill Rock'n'Roll-ballad sound to it. I think the song sort of lacks a lead part; to me it feels sort of like a karaoke backing track. Which also means I guess this is a pretty cool track for improvising over, I'll have to try that later! Also, I do agree that it fits the idea of sitting in a bar with music just playing in the background.
Not sure how well it fits the theme of the contest, to be honest, but other than that, pretty nice entry.
