Yes โ Iโve checked Mastermix for you. It is a legitimate DJ-only music service and could be quite useful for the type of DJ library you're building.
Mastermix DJ
What Mastermix actually offers
Mastermix is particularly focused on DJ-friendly versions and performance tools, rather than simply being another place to buy ordinary tracks. Their catalogue includes:
Extended versions
Radio/clean edits
DJ Edits
DJ Beats โ added beat-locked intros/outros for easier mixing
Re-Grids
Remixes
Mashups
DJ mixes
Themed collections
Retro and current music
MP3 and WAV
They state that their music uses original artist recordings and is licensed through PPL/PRS.
For your CDJ-3000X / Rekordbox setup
I think the DJ Beats and DJ Edits side of Mastermix is the part you should investigate most.
For example, their DJ Beats are designed with intro and outro beats added to the original songs, making it easier to mix tracks that weren't originally produced with a conventional DJ intro/outro.
That can be very useful when you're playing commercial House, Dance, Pop/Dance and older floor-fillers on your CDJ-3000X.
They also have dedicated Dance material including things such as:
DJ Beats Collection: 20s Dance
DJ Beats Collection: 10s Dance
Bass Bangers
Dance Jams
DJ Edits Collection: Dance
House USB Top Up
Nu Disco
90s/00s Dance
Mastermix vs Beatport
The important distinction is:
Beatport โ excellent for finding the actual club releases, extended mixes, underground House, Tech House, Melodic House & Techno, etc.
Mastermix โ particularly useful for DJ-friendly versions of commercial music, classics, edits, clean versions, DJ tools and tracks that are easier to mix.
So I wouldn't treat Mastermix as a replacement for Beatport. I'd treat it as a second source that fills a different part of your Rekordbox library.
One other thing: Mastermix says its subscription service is intended for professional/working DJs and music-oriented professionals, so check its eligibility/territory terms before subscribing.
