I'm talking about relatively new Korean songs.

Secret-only u personally thinks it is very suitable for ringtones.

Junior.-My lips.

Electroboyz-Ma Boy 3 (the girl's voice is quite suitable for ringing)

SHINee-Evil (sparkling fast-paced songs)

Rainbow-tell me, tell me.

Yun Si Yun-Want to associate (ost in the beautiful boy next door is a little fresh song)
