You've not told us what equipment you'll be using to play the clips. (A CD player of some type, such as a boombox? A laptop feeding into an amplifier? Something else?). It obviously makes a difference, as we don't know whether you want to end up with a CD with all of the intros on or a collection of MP3 files.
You've also not told us where you'll be sourcing the music from. (From your own CD collection? From Youtube? From somewhere else?). Once again, it will make a difference.
Please tell us you start and end points and we can then tell you how to do the bit in between. It might also help to know which software you've already got available to you. (VLC? Audacity? Something else?).
