I was browsing through tvtropes when I noticed a troper mentioning a hidden song in Worms World Party.
Speaking of Worms, there's a full techno remix of one of the main themes buried in Worms World Party, but only if you stop and wait on multiplayer match standings screen (after all rounds are played) for about a minute.

I've tried it (for several minutes even) but it doesn't seem to work. Can anyone confirm this?

Did you mean this?

Additionally, it's not hidden at all, and the music will start right away in the stats screen. You don't have to wait.

Odd. That song is actually familiar. I remember hearing it a long time ago when I used to play it, but now, after trying again, it doesn't seem to play. Oh well.
