Put in any song as long as it doesn’t have a lyric that says the title of the song. Also you can put any time limit to guess the song and the artist, you don’t have to guess the artist, it’s just your choice. Press the [I KNOW] button if you know this song, however, this will require you to say the answer. If you guess it wrong or ran out of time, you have to try it again.
The percentage is how much you were good at knowing the answer.
