This website is a bit imperfect, but SongTapper.com is still a fun way to waste time. If you hear a song you like but don’t know the name of it, you can use the spacebar on your computer to tap out the rhythm and it (allegedly) identifies the song.

I tried both “You Shook Me All Night Long” and “Back in Black,” and it couldn’t identify either. So basically the best this website can do is completely waste your time while you try to find a song it can identify.
