Query: Doesn't play correctly on a PC

This pair of CDs seems to be using some funky copy protection mechanism. Windows Media Player can't display a track listing or navigate through the tracks -- even trying to skip from one song the next will just drop you in the middle of a random track. The only option is to listen to an entire CD from start to finish. So don't plan to listen to this on anything other than a dedicated CD player...The presence of this copy-protection mechanism isn't disclosed anywhere on the outside of the album.The music itself is only so-so. Given the crippling copy protection, this album is hardly worth the money (even at a discount).
