This doesn't mean that you'll have a new music service in your Tesla automobile anytime soon, of course. Electrek's Fred Lambert points out that last year, Tesla owners found a Spotify app in the code, but the feature did not appear in US or Canadian autos. Tesla's cars already have a built-in streaming service powered by Slacker that includes a company sponsored DJ station. According to him, a branded streaming service (Tesla Tunes?) tied to the company's electric vehicles would only make sense if the auto maker can scale its car fleet up quickly and/or offer it as a freebie to current and future owners.

When reached for comment, a Tesla spokesperson referred us to an earlier statement on the matter: "We believe it's important to have an exceptional in-car experience so our customers can listen to the music they want from whatever source they choose. Our goal is to simply achieve maximum happiness for our customers."

Update: Elon Musk responded to the discovery with a tweet, calling TTunes a "joke." Whatever the purpose of the code is, at least it's not one more streaming service for us to subscribe to.
