IMO it’s not a matter what you can/can’t get away with. Bottom line is music created by someone else is under copyright and you should not use it without permission.
By using music in a video, you are creating an unauthorized copy of that music. The creator of the music holds the copyright and the right to determine who uses it and for what purpose. They also have the right to get paid for its use.
I know it seems like no big deal with a highly successful recording artist, but put the shoe on the other foot for a second. What if some tackle manufacturer liked your video so much that they copied it off of YouTube and used it in their latest ad campaign? Even if they put some fine print blurb giving you “credit”, how would you feel?
Contrary to popular urban legend, copyright is copyright. The use, commercial vs non-commercial use, etc doesn’t matter. If you didn’t create the work, you need permission to use it for any purposes.
