Shazam is a mystery to me.

I heard of it and thought wow, when I have a song stuck in my head but don't know the name, this App would help me to find it.

But it only worked if the real song is playing right now.

When that is the case, I'm either in a club and can ask the people there what it's called. Or I'm on a video/music streaming site where the name in 99% of the cases is written out.

Okay, sometimes I have a wrongly tagged MP3 or hearing some song in the background of an ad that I like to know the name of, but that happens only <4 times a year.

Are my music-listening-habits so different from the rest of the world?

Where do most people listen to music without the possibility to get the name of the work?
