I listen mostly to metal and japanese songs, but there are also times that I get into the mood for some pop music from the past. I personally despise the pop music of today.
Hmm.... 1) Code Geass - the entire series (3 times) 2) K-on - both season (4 times) 3) Angel Beats (8 times) 4) Clannad - both season (2 times) 5) The Melancholy of Haruhi Suzumiya - (almost every sunday)
