Individuals of a certain age may remember a time when a Sony Walkman was the technological, gee-whiz gadget of its time that set the standard for other portable music players. While much has changed over the years, the spirit of the Sony Walkman lives on today in the Sony Walkman Player app. Like other manufacturer specific apps included on Android devices in an effort to differentiate themselves, the Walkman Player is limited to Sony devices like the Sony Xperia S, Xperia T, and Xperia V devices. That situation has changed thanks to XDA forum member Rizal Lovins.
Using a copy of the app he extracted from his own Xperia S, Rizal Lovins has figured out how to get the app to install and run other Ice Cream Sandwich devices that have been rooted. Some quirks are still being worked out, but for the most part users can enjoy the visualizations, equalizers, animations, and other features of the music player app.
