Can’t get your fill of streaming music with the likes of Pandora, Spotify, and Rdio? There’s a new music service in town. Debuting for the iPhone and Android devices on Tuesday, the Beats Music app works more or less like its rivals. It acts as an online radio station to serve you tunes from your favorite artists and genres. The service claims access to more than 20 million songs, which you can listen to online or download to your device to listen offline. But unlike Pandora and similar services, Beats Music doesn’t offer a free, ad-supported version. Your only option is to shell out $9.99 a month for the privilege of subscribing. Fortunately, you can try the service through a free 7-day trial. After you download the app and sign up for your account, Beats Music poses a couple of simple questions. You’re asked to choose your favorite genres and three of your favorite artists. The service then cooks up a lineup of songs based on your preferences.
