HumHum

I recently had an idea to help me make music. I love singing along with random songs but I never remember their lyrics.<br><br>So I was wondering, what if there was an app that you could sing or hum a melody and the algorithm could recognize the song but more importantly highlight the exact part of the song where you’ve caught it.<br><br>Anyone here have any idea if something like this exists or if we can make it happen?<br><br>Edit: I was thinking of something very specific to humming, no lyrics, just hum or sing from memory the melody.
