Why Choose Mix and Master My Song?
What sets us apart from other mixing and mastering services
Direct Access to a Proven Pro
Unlike larger services where your song gets passed around, Matty personally handles every mix and master. With credits including Kelly Clarkson and Travis Barker, you’re getting a seasoned pro dedicated to making your track radio-ready.
Unlimited Revisions Until You’re Happy
Some services limit revisions. We don’t. We offer unlimited revisions so you can tweak your mix until it’s perfect. For first-time clients, unlimited revisions are completely free—no pressure, no hidden fees.
Fast, Streamlined Workflow
Once your files are in, we get to work right away. Most mixes are delivered in 3–5 business days, and revisions are turned around quickly so your project keeps moving forward.
World-Class Sound, Fair Price
Our studio is equipped with the same analog gear and plugins the big players use, but our rates are designed to be accessible for independent artists who care deeply about quality.
