[All] Seventeen included solo songs for all members in their 5th regular album

Seventeen releases their 5th full-length album Happy Birthday to celebrate their 10th debut anniversary
It has been said that each member's solo song will be included in this 5th regular album!
A total of 16 tracks, including 3 group songs including the title song and 13 member solo songs.
They say this is the album with the most songs in SEVENTEEN's album history! I want to see their comeback stage soon.
