Even with the No.2-known pieces were played by other performers and newly sung (Katey Sagal also has another piece contributed). These interpretations are great successful and act mostly completely different from the originals.
The asking price is on top of that also a lot cheaper than at No.1. What I do not quite understand is the pricing: The MP3 download costs 2 euros more than the CD, in the yes of the car-Rip is included. Well, me hell be right. ;)
