LSS: Last Song Syndrome?

I'm stuck to "Someone Like You" by Adele..
I've heard it from the radio and from that moment I can't stop myself singing the song which is the chorus part only and it goes like this..

♪♪♫..Nevermind, I'll find someone like you,
I wish nothing but the best for you, too,
Don't forget me, I beg,
I remember you said,
"Sometimes it lasts in love,
But sometimes it hurts instead,"
Sometimes it lasts in love,
But sometimes it hurts instead, yeah,..♪♫

yep! stucked in that line ahahaha but I love it though..
