Good news for music lovers, popular music discovering service, Shazam, has been updated in the Android Market. While the last update brought with it unlimited music tagging until Jan 1st, 2012 and social networking options, this new update brings with it music previews — something that has long been missing from the app. Now, after you or your friends tag a song, you can listen to a preview of the song to jog your memory and decide if you really want to make a purchase or not. While, I’ve always considered myself more of a Soundhound kinda guy (I like singing into my phone to find songs) these new features definitely make Shazam worth checking out.
