Ahh, Ultimix. They were my first introduction to remix services, and I own (and have played) more of their mixes than any other service. I consider them to be one of the "big three" - along with DMC and Music Factory - as the only ones of of the early pioneering / "golden age of the remix" services that's still going strong today.

As with most remix service productions, many of their mixes haven't aged well - but the ones which have are invaluable to me...and enen the ones that haven't certainly served their purpose for the time.
