OneMusic, a label of FirstCom Music / Universal Production Music had their CDs released with master numbers on the back covers.
This also applies to their LiquidTrax counterparts. LiquidTrax includes sub-mixes where music editors have the flexibility to create their own mixes.
In 1997, it started in the 1000s. For example, OM-AME 2 has the tracks with the master numbers, 1537 to 1546.
In 2002/2003, it went up to the 9000s with OM-ROC 33 having the numbers 9621 to 9640. Then it reverted back to double and single digits.
OM-ROC 36, 55 to 66. OM-ETN 8 in 2005, 688 to 699.
Did anyone highlight this before.
FirstCom Music did this on their vinyls, and Network Music had these as theme numbers on all of their albums up until 2006 when Killer Tracks acquired Network Music.
