Today, Billboard will announce its first music app awards at its Mobile Entertainment Live!: The Music App Summit in San Francisco. Eighteen innovative apps across most all platforms are nominated in best categories for artist, music streaming, touring, music creation, music engagement and branded music apps.

Whether you’re into singing, playing instruments, categorizing your music or listening to songs, there are thousands of music apps out there to explore. Among the Billboard nominees are music apps for specific bands (Linkin Park, T-Pain, Phish and a guitar tutorial app featuring blues guitar-ist Jimmy Vaughan) or for the music scene and festivals in specific cities.

Two of Billboard’s nominees I have mentioned in Get App-y before:LaDiDa ($2.99, Khush), developed by a former Oklahoman, Prerna Gupta, and her husband, Parag Chordia, is up for best music creation app. It continues to get attention for its ability to take anyone’s singing and make it sound better.SoundHound Infinity ($4.99, Melodis Corp.), nominated for best music engagement app, which “listens” to songs you hear and tells you what they are and who sings them. A nominee that has potential for fun is Mix Me In2 Taylor Swift ($1.99, Fried Green Apps). It is nominated for best music engagement app. If you like the country singer, you’ll enjoy this app. I can see the idea being successful with different artists. Select one of Swift’s songs (the app comes with two), and you can choose how you want to hear it — the original way or with styles such as acoustic, rock, urban, coffee house or piano mixes. Add or subtract instruments to make your own mix, or record your voice and sing along with Swift.
