Use Android Pay and you may find yourself with some free songs, or even a Chromecast. Google on Friday launched a new promotion for its mobile payment service that gives customers a chance to win some free products, according to Droid Life.

The program, which it calls the “Tap 10,” rewards smartphone owners that use Google’s Android Pay to purchase goods through Feb. 27. Customers that use the mobile payment service 10 times will get three free song purchases via Google Play Music. But there’s also a chance that Android smartphone owners could secure other prizes, such as a movie via Google Play, a Google Play streaming music subscription or in some cases a Chromecast streaming device, which retails for $35.

The deal is only limited to customers in the United States and there are additional details available in the fine print, such as a minimum 5-minute gap between purchases. But even if customers qualify, there's a chance they may not immediately see the promotion as Google is in the process of rolling it out.

Android Pay officially rolled out to consumer in September 2015, replacing Google Wallet, which first launched in 2011. It’s among a number of in-store mobile payment services that dot the smartphone landscape, such as Apple Pay and Android Pay. For 2015, in-store mobile payments are expected to reach a value of $8.71 billion, according to eMarketer.This year, mobile payments are could triple to $27.05 billion. And by 2018, 50 percent of consumers in markets such as North America, Japan and Western Europe could be using mobile payments on a regular basis, according to Gartner.
