stock20 royalty free music
Just a quick note that if you're producing slideshows, film etc.. and need music, Stock20 is having a deal on their entire library for $249. I realize that's not cheap, but when individual songs are normally $20 per and you get 1900 tracks, it's a fantastic deal.
Oh and this also applies if you're like me: not familiar with garageband and/or don't have the time to make your own tracks.
PS. I'm in no way affiliated with them - just spreading the reports of a good deal. It's on until Wednesday.
