"DR (or Dynamic Range) is a term for the degree of dynamic variation within a piece of music or album. Low values (e.g. DR3) reflect a high abuse of compression. Tracks that are DR3 have a range of three decibels between the average and peak program signal. A natural recording, with a low amount of dynamic processing, would have a much higher DR value (e.g. DR12+). The DR system is intended to avoid black and white judgment of dynamic quality. While DR7 is low for rock music or very low for Jazz, it is quite acceptable for electronic club music which has nowadays often values below DR4. All values above DR12 have generally a high dynamic quality."
