How often are you sitting in your car or at a restaurant and hear a song and think "I love this song, what the heck is the name of it?" Well with Shazam you can get that answer and you can get it QUICK!! This thing works so well and so fast... All you do is start the app, and choose a Tag Now button and after a few seconds of your phone 'listening' to the song you get a screen shot of the album, the artist and the song title. You can also get all sorts of other information with regards to the song but you can store the song and even buy it! There are also options for some songs that you can learn more about the artist or group by clicking on a link to take you to their myspace page. This thing works so well, as long as you can get a few seconds of unobstructed music (like no pauses or talking) you can often get any song, even classical stuff. Ive even been able to get songs recognized from tv commercials.. Definitely a must have app for your phone.
