Sprint today launched Sprint Music Plus, a new music application for both smartphones and feature phones that is designed to serve as a single destination for customers to discover, purchase and play music. Powered by RealNetworks, it includes individual and bundled offers of full-track music, albums, ringtones and ringback tones.

The music and tone manager allows users to create playlists, assign ringback tones to different callers and times of day, search for music, organize music, preview content and get recommendations based on their own tastes.

Sprint says customers can save money if they buy a full track, ringtone and ringback tone bundle at the same time. DRM-free full tracks range from 69 cents to $1.29 per song, and customers are charged on their Sprint bill.

Sprint points out that it offers an array of music options, including free apps downloaded from Android Market, BlackBerry App World or GetJar.com, Sprint Radio and purchasing tunes from Sprint Music Plus.

Sprint Music Plus is available for Android-powered Sprint smartphones from the Sprint Zone app and can be found on the home screen of BlackBerry and Java feature phones launched after May 2010. Devices introduced before May 2010 will have access to ringtones and ringback tones from Sprint Music Plus via Sprint Mobile Web (WAP).
