A person who is so enthralled with music that they talk about it with a passion usually reserved for sex. They sometimes reach semi-orgasmic states while listening or playing their favorite tunes! A musicsexual will always be found with their ipod plugged in, smiling, bobbing their head in sync with the music playing.

Literally everyone, ever. Including the writer of this definition.

Someone who can be aroused by music and who sometimes masturbates to music (and music only - no pictures or videos).
