Can you be addicted to a song?

Can you be addicted to a song?
I think i am, I listen to 'When You Look Me in the Eyes [original] over and over again.
That's the one Kevin sings in.
I have been listen to the song since 11:30 and it's now 2:58.

Kevin's voice is hypnotic and goes perfectly with Joe's and Nick's.
This song gives me chills.
And the lyrics are cute.
It drives me insane when I'm listening to the CD version and Nick's voice is lower and there's no Kevin. I get excited, then sort of disappointed. (Though i love both versions like no other)

Is this normal?
