Program to Slow Down Songs

Hiya,

I'm trying to transcribe Fade to Black by Metallica to the piano for something for school, but part of the beginning solo is too fast for me to make out the notes. Does anyone know of a program (preferably free) that can slow down songs without changing the pitch of the notes? I have Audacity, but I don't know if it can do that. If it can, can someone show me how? Thanks.

Sheet music (or tabs) are your friends.

It's more fun and convenient for me to play by ear. Anyways, I found out that Audacity CAN slow it down. Mods can close this now.
