Just got an email from YouTube that read in part:
Your video, Ignite The Night (Part 1), may have content that is owned or licensed by UMG.
Hmmm. Turns out part of the music for the show is the Supremes, “Stop In The Name Of Love” (right at 6:06 in the video) and now there is advertising shown in the sidebar on the page for that video as well as links to download the Supremes song and also an overlay ad for downloading the song.
Interesting.

Wow. That’s really something.
