The chain has teamed up with hip-hop legend RZA to create a new web app that lets you make actual music with your order. Best of all, you get free food out of it!

Chipotle launched the “immersive” musical experience, dubbed SAVOR.WAVS, on Wednesday morning, complete with an elaborate teaser video featuring the multi-platinum artist and Wu-Tang Clan creator.

“We collaborated with @RZA to turn your favorite Chipotle order into a symphony of flavor. Get a taste: http://chip.tl/savorwavstw,” Chipotle tweeted.

Basically, the website lets you compose a song based on your go-to Chipotle burrito, burrito bowl, tacos, or salad order — just by selecting the ingredients as if you were ordering one online. Each ingredient you select adds a unique sound composed by RZA, resulting in a customized flavor symphony and colorful visual experience for any possible ingredient combination on the menu. For example, avocado is represented by the viola, which when added with the instruments representing other ingredients used to make guacamole, creates a melody that’s used in the song. Fun, eh?

Wait until the end to get your most awaited free food deal. Once you’ve tapped in your order and listened to the song paired with the visuals (about 45 seconds), you’ll be redirected to a form where you can enter in your contact info to receive a one-time buy-one-get-one (BOGO) deal for burritos, burrito bowls, tacos, and salads. You’ll get the digital coupon a few seconds after submitting your info.

Chipotle is giving away 4,250,000 of the coupons, and this deal is good until August 31.

Make your burrito sound better!
