I can't stop listening to Wake My Up by Avicii featuring Aloe Blacc. It's been several months of constant radio plays and I'm still in love with it. ^^
There is more than few of these songs that I just cant stop listening to. here few examples: Guns for hands by twenty one pilots. one of my favorite bands and a song that is stuck in my head every now and then.
and for example im listening to imagine dragons' "radioactive" very much these days, its damn powerful song. also i cant stop listening to "should i stay of should i go" by The Clash, awesome song
I have to listen to this song at least 10 times before I go to sleep and at least 20 times during the day. It always makes me think of Spencer Reid from Criminal Minds after the Zugzwang episode for some reason. :)
