Okay. Actually, different people have different taste. So it's
hard for me to list them right here. I wouldn't want to recommend
Korean songs, which in the end, you don't enjoy listening to them.
So, I'll just present certain songs which I may find them unique
and nice to listen to.
Here are the following: ~
Sarang Eh Mal (Classic Version) - Seo Jung 
Basically, this is the Korean version of Yue Liang Dai Biao Wo De
Xin sang originally by Terresa Teng Li Jun.
Bi's 3rd Album is good too!
It's Raining, My Groove, Nan, Cha Jah Yoh is not bad.
Songs by Chae Yeon has some techno and pop beats in them. So worth
listening and grooving with them.
Fly to the Sky's entire Album is something like slow rock. The
songs are considered melodious. Not bad either.
If you're looking for one of the best soundtrack to download, try
Stairways to Heaven. The entire album is loaded with nice melodies.
Ave Maria is one of the great hits inside.
As for the soundtrack Uri Jip, I'll recommend track 2, 3, 7, 9
& 12.
Wheesung's album has a little bit of funk inside. For K-pop lovers
in fact.
Ggot Bo Da Nam Ja by Kim Yun Woo is a Korean version of the Chinese
song Qing Fei De Yi. Also the soundtrack of Liu Xing Hua Yuan
(Meteor Garden).
Once Upon a Day by Kim Bum Soo will sound very familiar to you.
Worth requesting.
Last but not least, I'll recommend songs sang by Zero. Just look
for any songs by Zero, and I think you'll be very captivated by his
voice.
In fact, all the listed songs I have are very nice songs. They just
need to be appreciated by listeners.
