Research In Motion (RIM) and Amazon today launched Amazon MP3 for BlackBerry smartphones in beta in the U.S. The new app gives BlackBerry smartphone users access to Amazon's entire music catalog of songs for easy purchase and download.

Amazon MP3 for BlackBerry smartphones lets users discover songs, artists and albums, then lets them buy and download tracks from Amazon with just a few clicks. The app also offers delivery options to suit all data plans, so tracks can be downloaded over Wi-Fi or cellular networks. Users are able to share their latest musical finds with their friends by sending comments and links for specific tracks through BBM (BlackBerry Messenger), email, SMS, Twitter and Facebook.

Amazon MP3 for BlackBerry smartphones is also integrated with the universal search feature on handsets running the new BlackBerry 6 operating system. Users can start typing the title or artist from the home screen of their BlackBerry smartphone and Amazon MP3 will appear as a search option.
