Can we post our mixes publicly as a part of our portfolio?

Everyone here has already done so, and streaming uploads were required to enter the contest. The song has been cleared definitely. YouTube knew my video was copyrighted material but mentioned the rights holder had allowed it to be shared. Obviously I would refrain from claiming any kind of original work or involvement with the artist, and I’d be transparent about how you obtained the multitracks, but otherwise have at it.

That’s the whole reason I did a mix because it sounded like a great song to have in my portfolio.
