Taeyang - Let Go
He's got that beautiful voice and it just has such a nice sound to it that sets the mood; granted the lyrics are along the line of "I'm lost without you," which can be a downer, but I think it is still very romantic
B.A.P - Body and Soul, It's All Lies
This song... It is dripping with romance and sexual nature. Definitely a must have; don't believe me? Just listen and read those lyrics... Whew, I need to recover. It's All Lies is a bit sad but still has a romantic sound
BTS - I Need U, Butterfly, House of Cards, and Dead Leaves
So ignoring the video and lyrics for I Need U, one can not deny the seductive sound to it. And Butterfly is lovely. House of Cards and Dead Leaves, oh my god yes!
HyunSeung - I Said I Love You
I couldn't find anything more than the audio teaser. But it is soooo good! It isn't the loviest; in fact it's kind of the opposite lol but still has a sound that fits the seduction/romance theme
Sorry if I went a little crazy and added a lot but I really like to share music! So do the challenge if you haven't!
