The Recording Academy has released a collection of amendments to the guidelines for next year’s Grammy Awards, including the inclusion of streaming-only projects, which will now be eligible for award consideration. Previously, the awards could only go to recordings that were available through general distribution or digital recordings and downloads, which ruled out streaming-only music.

This change most directly affects the world of rap music, as the genre’s much-used medium of mixtapes are now eligible for Grammys, including Chance the Rapper’s recent Coloring Book, regarded as one of the year’s best albums so far. As Stereogum points out, Chicago blogger Andrew Barber tweeted about the amendment, saying simply, “Streaming only projects are now available for Grammy consideration. I’ve been working on this for three years.”

Senior Vice President of Awards for The Recording Academy Bill Freimuth says, “I’m proud of this year’s changes because they’re a testament to the artists, producers and writers—the people who rolled up their sleeves to shape the proposals and, in turn, the future of the Grammys. It’s exactly what they should be doing. It’s their award.”

Other amendments include decreasing the number of categories in which members of the Academy can cast a vote, splitting the Best Blues Album into two categories: Contemporary and Traditional, amended Best New Artist eligibility guidelines and more. Read the full changes here.

The 59th Annual Grammy Awards will take place on February 12, 2017, at the Staples Center in Los Angeles, CA.
