One of the most popular mobile apps is Shazam. It is used to find out the name of a song. Basically you hit the listen button on the app and it listens to a song and is able to run that through a database and determine the name of the song. Once you start using it you will wonder how you lived without it. Especially if you are a music lover. It also links up with youtube so you can watch the video or listen to the song on spotify. Also it will list the artists tour information. It’s just really cool. Check out this video review to learn more.
