Reason is that artwork thumb chunk for 200x200 px is 80000.
80.000 * 30.000 songs = 2.400.000.000 which is roughly the upper limit for MHNI.offset (that is integer) and thus overflows to negative value.

This causes artwork not showning correctly in iPod, and also MM fails to scan or sync it (because of the unexpected negative offset value).
