I can always tell what kind of mood I'm in/have been in when I review my last.fm listening charts. It's never obvious at the time but when I review my last.fm account, it all becomes very clear. My Top Ten of 2015 was a lot of dreamy, romantic tunes. Not so far this year. Apparently, I'm pissed. Really pissed.
These songs come directly from my listening charts on last.fm and the albums had to be released in 2016.
