The popular music service from Yahoo! has undergone some changes.

As of yesterday, Yahoo!’s music service, Yahoo! Music was upgraded and was renamed to Yahoo! Music Jukebox. The new service gives consumers an optimal listening experience by utilizing popular features from both Yahoo! Music Engine and Musicmatch Jukebox.

“This new version of the Yahoo! Music Jukebox enables our users to take advantage of the combined strengths of the Yahoo! Music Engine and the Musicmatch Jukebox in one fully-integrated experience,” said Dave Goldberg, vice president and general manager of Yahoo! Music. “The merged product reflects the hard work of our engineering and product teams in building a best-of-breed media player for digital music fans.”

The new features of Yahoo! Music Jukebox include a new audio equalizer, and improved playlist and usability enhancements. For $19,99, users can buy the premium features of Yahoo! Music Jukebox Plus which include faster ripping and burning, custom CD printing and audio enhancements for imported MP3 files.

Key functions are now more accessible through consistent right click and tick menus. Other features are now just a click or a key press away. Playlists are now easier to maintain as Yahoo! Music Jukebox will automatically store them and make them accessible from any PC. Users can also search for playlists to help them find other music fans with similar tastes and preferences.

More than 2 million songs can be played through Yahoo! Music Unlimited subscription service and transferred to portable devices. Yahoo! Music Unlimited is available for an annual fee of $59.99 or a monthly subscription price of $6.99.
