If you’ve ever wanted to know just how bad your singing voice is compared to Freddie Mercury‘s, YouTube is ready to tell you.

We kid. But YouTube really has launched a device that compares your singing to the powerful vocals of Queen’s iconic frontman. The FreddieMeter, created in partnership with The Mercury Phoenix Trust (a charity founded by Queen’s surviving members dedicated to fighting HIV/AIDS), allows you to test your vocal skills on four Queen songs — “Don’t Stop Me Now,” “We Are the Champions,” “Somebody to Love,” and of course “Bohemian Rhapsody.” You simply sing into your device’s microphone, and the site will produce an analysis of your performance, showing you how well your vocals match up with Mercury’s.
