Pareidolia,
These indents are part of the recent AMTV launch. Wow! did I just see
Taylor Swift in those scrambled eggs, was that Lil Wayne dripping with syrup
on that short stack! See for yourself.

These run up to 8 times per hour which also work as sponsor beds and video
premiere opens.

What is AMTV?
It’s real music for real people who want to start their day off right. It’s
six straight hours of music videos and music content, every morning from
Monday to Thursday- 24 hours every week. No loud host, no UGC dance moves,
any flashy lights or pyrotechnics, and definitely not the same videos played
over and over again.
