DO you think somethings wrong with me?

I have been really addicted to this song for well over a year now. But lately, I have been listening to this song day and night on youtube, my ipod, my phone. I dont even study that much, I can't concentrate in my studies, its so addictive. I can usually study and listen to music at the same time, but not with this song. I can't stop listing to it, I am getting worried coz this has never happened to me before. Is this normal? I always clap the rhytm and when im alone at home I just close my eyes and dance to it. Im also a drummer, so i have tried to drum it. then i realized that i am also obsessed with the guitar riff in the song. (its called 15 step by radiohead), the song makes me feel really really good.
