"If this song was released by other group it would be a hit... why can't people give SONAMOO a chance?"

A lot of attention has been placed on SEVENTEEN and Super Junior's comebacks this week, but another group that also returned are the lesser-known SONAMOO.

The TS Entertainment girl group have been making a real effort to stand out more over the past few months with their Happy Box project, which is an extended album release roll-out consisting of several new singles and eventually, a new mini-album.

The second Happy Box single, "I (Knew It)," dropped on Monday, causing many fans to take to Twitter and YouTube to talk about how underrated SONAMOO are.

"If this song was released by other group it would be a hit...why can't people give Sonamoo a chance?" wrote one fan.

Another said: "They are really underrated but so talented and I hope this song has more people take note."

On the bright side, SONAMOO's Euijin is receiving some attention right now after becoming one of the standout stars of KBS survival show The Unit. Hopefully her growing profile will turn the spotlight towards SONAMOO and finally get the group the recognition they deserve!
