UE Music Library
UE Music Library is a branch off Logitech Media Server, with severely limited functionality. It was introduced by Logitech in August 2012, as Logitech abandoned the Squeezebox line in order to pursue the Ultimate Ears (UE) line of network music players instead.
UE Music Library is not compatible with any Squeezebox units, LMS, or any earlier hardware or software products in the Squeezebox line.
As of September 2012, the Ultimate Ears line of network players comprises only one product, the UE Smart Radio. Hardware-wise it is very similar to the Squeezebox Radio, which can be turned into a UE Smart Radio by installing a different firmware. This process removes a lot of functionality, and can not be reversed.
