Besides j-pop, I mostly listen to pop & urban music like RnB / hiphop. I also like some electronic music genres.
I'm not too picky about genres, there might be a song or artist from almost every genre I enjoy.
only types of music I can't stand are metal & rock
I think the best types of summer music are upbeat & catchy songs
My fave new summer-y songs at the moment:
Eve - Tambourine
Tamia - Daydreaming (DJ Hasebe remix)
Daddy Yankee ft Fergie - Impacto
Tanieya - Mop the Floor
Chilli - Gameproof
Daddy Yankee feat Nicole Scherzinger - Papi Lover
