1. Aside
2. An Encore
Compared to the first two, this one is less popular, but
-I agree. And one more thing, SHINee's side-tracks are all very nice.
-I really like Don't Let Me Goㅠㅠ
-I freaking love Don't Let Me Go... I like Aside and In My Room, tooㅠㅠ
-I love all the songs mentioned here, especially Aside
-Who Waits For Love, Kind, Area, In My Room, etc. SHINee's discography is filled with good songs only.
-Every time I recommend Close The Door to my friends, they will 100% add it to their playlist right away
-Hul... It's my first time listening to An Encoreㅜㅜ I love itㅜㅜ
-I'm not a fan but I somehow choke on my tears every time I listen to An Encore...
-I feel like tearing up every time I listen to An Encore. It just... touches your heart.
-It's hard to pick one favorite song from their side-tracks. All of their side-tracks are that good.
-I once promoted Love Sick and everyone loved it. I have never met anyone who doesn't like that song.
-An Encore and Love Sick are my favorite side-track of SHINee.
-If you like ballad songs, go check out SHINee's Quasimodo.
-SHINee's side-tracks are indeed that good...
My favorites: Odd Eye, Aside, Selene 6.23, An Ode to
