There are many popular b-side tracks of groups out there. However, the b-side tracks of not so famous groups need recognition too. Here is a list of them that you might be interested in listening to.

Stellar's "Guilty" - This song is part of their "Marionette" album which was released in 2014.It has that gloomy and haunting feel. It is like the continuation of their famous song "Marionette".

Rainbow's "Bad Man Crying" - Rainbow before disbanding has blessed their fans with this amazing ballad! This song was released together with "Black Swan". This song is really good. I always think what if Rainbow promoted this one; it might be on the charts.

Nine muses "OMG" - Nine Muses before the tragic 2014 has had many good b-side tracks in their "Primadonna" album. However, I'll put "OMG" because it is my favourite. "OMG" is a really cute song but not cringe. I do wish they made a music video with this one. Other honorable mention from Nine muses is "Living Person".

Spica "With You" - Now, Spica has many high belting songs but "With you" is one of their more chill songs. It has a nice melody and it has acoustic sound to it which is really nice.

15& "Not Today Not Tomorrow" - 15&'s "Sugar" album is a gem that Kpop fans need to know. All of the songs in there are amazing and it was hard to choose one. However, I choose ""Not Today Not Tomorrow" because it is not their typical ballad or sad song.

Fiestar "Hello" - This Fiestar's track is from their "Black Label" album that also contains "You're Pitiful. Actually, all of the songs in here are really good. Fans should definitely give a listen to Fiestar's b-side tracks!

Another one is Dalshabet Subin's first solo track in their album BBB "Just Pass" featuring BtoB's Ilhoon. Subin has definitely one of the nicest voices in kpop but Dalshabet is so underrated and forgotten that is it so painful. Listen to the song and other Subin's solo releases!

Do you know any other b-side tracks from girl groups that are really good?
