I'm listening to SNSD's discography from beginning to now and while OT8 has decent songs like "All Night" you then have mediocre songs like Holiday, Party or childish songs like "Lion Heart".
I don't mind OT8, but SNSD now just feels forced and fake. I mainly like OT8 because I like Sunny. Holiday Night while a good pop album, SNSD needs Jessica.
I'm an OT9 all the way
