It's part of a promotion for AT and T. What a fun idea. To promote blink-182's first single in 8 years, they searched YouTube. Any video that used blink-182's music without permission was given consideration. They took clips from the selected videos and made one for the single, Up All Night. They are calling it the fan montage. It's a lot of fun.
Embrace your fans. How exciting is it for a fan to see themselves in a "real" blink-182 video?
