Many songs from the dream pop genre are sexy to me. Beautiful vocals, often a bit breathy or sleepy. It's like a lullaby for grown ups. I could go on and on w/ those types of songs. I'll try to limit myself. Here's one from The Sundays, I much prefer their rendition to The Rolling Stones' version.
Another from the same band for good measure. Sigh. Harriet Wheeler, why did you quit singing?
