Team Fortress 2 Spy kit Soundpack - Basically, as I would think, ALL of the sound effects for the spy? And the best part, they aren’t 5 minutes long, like some other soundpacks would have, so it is possible to use with MSN and not hate your life.

Starcraft Sets Soundpack - About 5 different sound effects, but the only one I particularly enjoyed was the nuclear launch one.

Metal Geat Solid - Probably the most suitable MSN noises so far, and just cool. Too bad there’s only like 6.

Final Fantasy Soundpack - Once again, the only one I think can be used for MSN without cutting it is the victory sound effect xD

Age of Empires Soundpack - That is if you want to annoy yourself to death, you’re most welcomed to. This will assist.

Warcraft 3 Soundpack - This can be hilarious if used for the right cause.

Worms Armagedon Soundpack - something personally I would enjoy, but…. in spanish?

Penny Arcade Winamp Skin - I don’t know how many of you would be using winamp, but very and very nicely done from what i saw

Castle Crashers Winamp Skin - Well, what more can I really say.

Sooo some productive minutes of boredom

Growl for Windows is currently in beta so it’s feature set and API aren’t finished yet but the developers are working on a full API.

Thanks to Lifehacker for the heads up and the screenshot.
