What is the worst recorded CD you have?

Bought a Japanese Young Rascals Greatest Hits cd that's extremely difficult to listen to. What a shame.

Led Zeppelin Reunion live cd. Terrible, terrible , terrible

any RUSH live album from 2002 on. When will they learn that Alex cannot mix. Terrible, compressed to death. I am finding that bands ( like Rush) who are doing the "silent stage" thing ( all direct, no amps or stage monitors) have terrible sounding live albums. 

Arturo Toscanini conducting the NBC Symphony Orchestra in Beethoven's 9th Symphony. Great performance of course (with Robert Shaw handling the Chorus), but the sound is like that of a bootleg---terrible! There are more recent CD's of the recording than mine now available, which I need to hear. 

U2 / The Joshua Tree (1987) such a great album but very poor recording sounds like transistor radio from the 70's .
