I know, more music, but this one has a point dammit! These are songs that you would use to either a) seduce or b) put on for ambiance when you get to your..ahem...business...
Mine are
Marvin Gaye - Sexual Healing
Enigma - Principles of Lust
DMB - #41/Say Goodbye
Type O Negative - Love you to Death (not as morbid as it seems)
Incubus - Stellar (listen to the lyrics and you'll know what i mean)
