"Mmm..Bop" by The Hansons, i know the entire song and i absolutely love it, probably because i grew up with my big sister who was a complete freak about them when she was 13-14, she had posters, cds, singels, dvds, clothes, mouse-mat and even covers for her bed, All "The Hansons".

Thanks to that the song got stuck in my head and it combined with good memories of hanging out with my sister when i was younger so now i cant stop loving it, and im a 19 year old dude.
