Foobar2k Support (w/out the winamp emulator plugin.., I feel that the COM plugin works better than the winamp one)
1. Install this -

2. Create a file called fb2k.player.js and put it in the now playing's player folder in the script directory (Default: C:\Program Files\Messenger Plus! Live\Scripts\Now Playing\players).
Input the data found here:

And you should be ready.
Note: No support, the sendsong feature doesn't work for some reason. But at least it does what it is supposed to. Also, this assumes that FB2K is always open as long as Messenger is (i cannot use the interop.call to check if it's open for some reason..it's due to the GUID thing I guess)
