To open a specific view, set iType to the view type.

To open a specific path, set iCollectionPath, music player will select the best matching view to display the result.

using iCollectionPath/iCollectionPlaylist + iType is supported, but not recommended since music player already selects the best matching view to display the result.

If the client wants the command to be processed by a specific music player instance they should set iCmdForward to a value defined by TMPXCmdFwdType. The default forwarding is to stand alone musicplayer (it'll be launched if it doesn't exist).
