I am very new to Kpop and I have been having a lot of fun discovering different artists and songs.  So far I have been listening to a lot of upbeat music that makes you want to dance but I am sort of in the mood for something slower and more gentle.  Does anyone have recommendations for slower songs--something beautiful and/or relaxing?

Thanks!

check out Xia Junsu and Zhou mi. both do really up beat stuff and ballads but also have alot of songs right in the middle.

Kim Jaejoong also has some slower stuff.


solo artists are probably the best place to start. often the group's slower stuff tends to sound like 90's b-list boy band junk. not all of it, but a lot of it.
Thanks so much for the recommendations cityhunter83, this was exactly what I was looking for.  
glad to be of help
One of my favourite slows songs is by Kyuhyun- At Gwanghwamun

@LaughingCheshire-thanks for the recommendation! This fits perfectly into what I was looking for.

@ladymay-From what you recommended I absolutely loved If You by BigBang and At First by JJCC, so thanks for the suggestions:)
Well I would suggest simply to use OST from series you're watching or about to watch :), there's a huge number of slow jammers in it.
Here are some more suggestions:
Let it Rain - Epik High
The Answer - Kim Sunggyu (from Infinite)
41 Days - Kim Sunggyu 
We were in love - Davichi & T-ara
How to love - BEAST
Blind love - CN Blue (actually a Japanese song but CN Blue is Korean so let's count it as kpop, shall we? :P)
Broken - Seo In Guk 
Moonlight - GOT7
Let me Know - BTS
24/7=Heaven - BTS
Hold me tight - BTS
Borders - Amber (from F(x), this song has been released 2 days ago & is totally sung in English :3)
One of these Nights - Red Velvet (also quite recent - released 10 days ago)


A lot of OSTs fit in that category too :) 
Just to be safe, I recommend not watching the videos, in case you encounter spoilers of dramas you might want to see ^^
Suddenly - Kim Bo Kyung [City Hunter]
Don't forget - Baek Ji Young [IRIS]
Because My Steps Are Slow - Shin Yong Jae [Faith]
All of a Sudden - Krystal (from F(x)) [My Lovely Girl]
Echo - Every Single Day [I Hear Your Voice]
Eternal Love - Michael Learns to Rock (technically not kpop though, I think the band is Swedish..? but the song is so good T-T) [Healer]

Hope it helps :3
