Weezer put out an invitation to their fans to:
"Step up to the challenge and show them that your mix is the answer. Use the stems to create a remix or cover the song in your own style to show the band what you've got. Weezer will be hand-picking the top submissions to be released as an official compilation and the winners will be paid appropriate royalties based on their version being on the release."
This is great because it gives the fans the opportunity to win something great and be creative with the music they love while also promoting Weezers newly released album and single. It's so cool that the band wants to see what kind of re-mixes their fans can come up with using their single as a base. It'll be interesting to follow this and see what the grand winner's song sounds like, who knows, that grand winner can become the next master producer.
