Anime op/ed/ost that you like, but haven't watched/wouldn't watch that anime?

Is there an anime like that?

I don't have any such anime guys xD I usually listen to openings and ending from the anime that I have watched already.

I would say the K-on series. Though I have a lot of music from series I still haven't gotten to yet.
