I tried this out but it didn't seem to pick up most of what I tested with. Maybe I suck at humming the tunes? I tend to use dee's, should I replace them with doo's? Day Tripper was one song I could get to consistently work, since it has a very distinct riff.
I tried a song that I remember hearing on the radio in high school once that I have never been able to find and it has been so long I probably am singing the one line I think I remember completely wrong. It couldn't figure it out except one time it suggested "Carry On". The problem is it only mentions the song name, not the artist.
