Those are nice as well but not really my type. I prefer songs that has piano, electric piano, bells, crystals, gliding basslines, moog lead etc. Slow and romantic. Anything that is like Boy 2 Men and All 4 One. I mean like real singing. Back up vocal harmonies. The ones you posted are more like Usher and B2K and them. A little quite sexual. I like something like these here...
