AceShowbiz - Sheryl Crow has slammed U.S. Recording Academy bosses for overlooking her record "Threads" in the nominations for the 2020 Grammy Awards.

Sheryl released the star-studded album of collaborations featuring the likes of Keith Richards, St Vincent, Stevie Nicks, and Eric Clapton to strong reviews back in August.

But the record failed to bag even a single nod, even in the rock categories on a list of nominees that was dominated by young artists like Lizzo, Billie Eilish, and Lil Nas X.

In a now-deleted tweet, the "All I Wanna Do" singer took the organisation to task, writing, "Hey @RecordingAcad didya even read my album note? Greatest story ever about a girl listening to her heroes' records & dreaming of going off into the world to play music... then making a record with all of them, for cryin out loud!"

According to Variety, she also mocked the Grammys' perceived ageism with the hashtag, "#grammysforoldpeople."

Country star Brandi Carlile, who picked up three nominations on Wednesday, November 20 without putting an album out, and appears on Sheryl's record on a cover of George Harrison's "Beware of Darkness", backed her pal in a reply to her angry tweet.

"You made an absolutely once in a lifetime album and I love you," she added.

The 57-year-old is a nine-time Grammy-winner, but has not been nominated since 2009.

Another star who unexpectedly wasn't nominated for a Grammy this time around was 20-time winner Bruce Springsteen, his latest record "Western Stars" garnered no nods - despite again being acclaimed by critics on its release.
