Love This ! ... every time I think I've heard the best 2:22 they step it up again 

I've done my share of knocking "pop", but think it's a shame to entirely write off any style of music.  I find individual songs I like in just about any genre, and artists whose talent I admire even though their music may not work for me. 

In GPN's case . . how exactly do you stuff their music into a one-size-fits-all box anyway ?  
Besides pop is just short for popular and that continually changes.  So hopefully they'll ride a "popular" wave and then become a timeless classic like the bands/artists who have been around for a long time and are still drawing new fans today. 
Won't touch the t-shirt&amp;jeans vs current look issue because don't think it has anything to do with the music,  and because I just really don't care.
