Thank you very much, that's probably enough info to sort it out.@gommer
What you want to do is not possible. The reason is that the moment you press a key, the status changes from "PlayingMusic" (for example) to "Action".
What you can do is add a message with status "Action" for each window in the My Music plugin that has the same content as the message with status "PlayingMusic".
Then, as long as you stay inside the "My Music" menus, the display will keep showing the music info...
To get the window ids of the My Music windows, you'll have to dive into the MP code. Specifically the Core\guilib\GUIWindow.cs file...
