I just got the new Windows Media Player 11 Beta and it’s pretty cool. The upgrade broke the Turn on “What I’m listening to” feature in MSN / Windows Live Messenger. Here’s the steps to getting Turn on “What I’m listening to” working again.Click the Now Playing menu (not the button).
Scroll to plug-ins – Other – and make sure that “Windows Live Messenger Music Plugin” is selected. I’m guessing there’s similiar option for MSN Messenger Music Plugin, but I can’t say for sure.
