Hi, I am Inspector Cachet and I am here to help you with your detective skills. 
This lesson is about online research. Sometimes it can be fun, sometimes it can be lengthy and tedious.
The puzzle
I discovered a mysterious recording, labeled 'The Best', that was left by some suspicious persons. The recording appears to be an unpublished song with a music video. I don't think the clips belong to this song, but look very familiar. The suspects also seem to have left some stash hidden somewhere. Hopefully, the video will help you solve the case and find the stash.
The recording can be found here.
