Pontiac Township High School Music Department 2004-2005 - backed up 2026-10-02 from a CD-R that is degrading.
19 tracks, 72:19. Track names and ensembles were taken from the disc label (cover.jpg).

Tracks 1-2: two raw reads were bit-identical, so they are exact.
Tracks 3-19: repeat reads differed (the drive silently conceals damaged audio, getting worse toward the end of the disc),
so each track was read 5 times and every sample is the majority/median value across the reads.
Sectors with no 3-of-5 majority (least certain; differences are usually small):
  t4 0.30%, t11 0.01%, t12 1.03%, t14 0.06%, t15 0.02%, t16 0.22%, t17 5.48%, t18 6.74%, t19 2.16%; all others 0%.
Tracks 17-19 are the most likely to have audible clicks or glitches.
