If you heard “Bohemian Rhapsody” before you knew about the legendary band behind it, you might’ve thought it was performed by a full-scale symphony orchestra and choir, with a little help from an electric guitarist or two.

While the instrumentals and back-up vocals undoubtedly make the song an operatic rock classic, it’s the unparalleled vocal talents of frontman Freddie Mercury that send chills through your whole body—and the same could be said about pretty much every other Queen song, too.

To celebrate the legacy of Mercury, who passed away from AIDS-related causes 28 years ago this past Sunday, November 24, YouTube and Google Research teamed up to develop the FreddieMeter, an interactive karaoke tool that compares your voice to his.

After choosing one of four song options, which include “Somebody to Love,” “Don’t Stop Me Now,” “We Are the Champions,” and “Bohemian Rhapsody,” and enabling microphone access, an instrumental version of the song will begin to play. The AI-powered FreddieMeter will analyze your timbre, pitch, and melody as you sing along with the flashing words, and you’ll then be given a scorecard that compares your voice to Freddie’s.

Though we don’t have any statistics on what’s considered a respectable score, CNN reports that one of their editors (who chose to remain anonymous) finished what was surely an admirable attempt at “We Are the Champions” with 11 percent.

The FreddieMeter was created with The Mercury Phoenix Trust, an HIV/AIDS-fighting charity founded in Mercury’s memory by fellow band members Brian May and Roger Taylor, along with manager Jim Beach.
