Pffft! Download CD-Ex. Use the split feature (I forget what it's call off-hand, but its' the button that shows a piece of he CD cut out). Just highlight the tracks you want to combine (it merges tracks, too), click that button, rename it to whatever you want, and then click OKAY (or whatever it is).
Do you own the CD, though? If you don't, CD-Ex won't work.
