Welcome to PEEL, Chrusinator99,
I guess you have searched for this, very well done! Not many new members know how to do so.
Sadly our search function gives you the oldest threads as the first results. What I mean is that you just bumped a thread that is nearly 5 years old, and not a single member of these above posts here anymore.
About the Urls, have you tried CGEF
, or The Fry Hole
? They have few sound-bits.
You won't find whole songs (in the meaning of songs that the Futurama crew had to license themselves), like "Don't you forget about me" for Luck of the Fryrish, though. Downloading them is illegal, due to those copyrights. So the discussion about downloading them is forbidden here.
