The "Yahoo® Music Engine Remote Control" is a library, written in JavaScript, which can be used by Yahoo® Widget Engine (YWE) Widgets to communicate with the "IRMPRemote" Yahoo® Music Engine's (YME) SDK class (More information about the "IRMPRemote" class can be found in the YME SDK site). You can use this library in order to send/get data to/from YME. The communication is being done using COM calls which the library uses to communicate with YME. The library also supports event notifications so your Widget can be notified about events which are sent by YME.
