SEOUL -- Boy band EXO has made a grand comeback with its new album "OBSESSION" by topping iTunes' albums chart in 57 countries.

The six-member band's title song "Obsession" has also garnered explosive popularity online, with its music video watched 9.1 million times on YouTube in less than 24 hours of release. 

"This song is going to be stuck in my head all day at school" said Ashley Diaz, a YouTube user. Another user "Erica Hernandez" said: "I haven’t liked their other stuff but this song and mv are really good!"

Currently, EXO is active as a six-member team because two members Xiumin and DO are in the Army for their mandatory service while Chinese member Lay is engaged in overseas activities.
