Make it so any user can manually set the tempo/beat, not just change the speed.
I see that you have a premium feature for changing the tempo. You should also include an option to manually set the beat for the whole song. I was just listening to a live song on chordify and it gets the tempo right at certain points and wrong at others. Let users tap the beat (mouse click or space bar) for the whole song so that it can be very accurate even if tempo changes in the song.
Thanks for your idea! We’ll bear it in mind and keep an eye on the votes!

P.S. similar to https://chordify.uservoice.com/forums/179340-general/suggestions/9170774-make-sure-tempo-changes-in-a-song-are-correctly-tr, but different solution is suggested.
