My Take
It is a great tool if you already have your lessons planned out and know what lessons go with the music videos too.
How I Use It
I would watch through all of the videos to see if any of the videos contain information with a lesson that was already planned. It is hard to see if your lessons will go with a music video though since the lessons are organized by music video and not the educational aspect. The music videos are awesome though and can spark interest in students to learn different parts of what went into creating the music videos.
