Well that's what I said no? Either rip them off the CD or find them online.
Even if windows can read the CD-DA, Tsukihime won't use the CD-DA from the CD, it has to be ripped anyway.
Here, for the folks who can't figure out how to rip the music from the disk:

They aren't the music from the disk, but from Ever After, which are remix of the originals, higher quality and all. I've manually lowered the dB of all the tracks too, because Tsukihime doesn't allow volume control and it would be extremely loud otherwise so it should sound just right.
