Yes, that's one of Google's apps, as well as YouTube and the Chrome browser.  You can also use your phone's music player app, but I think Google Play Music has better features for listening to Internet radio, such as being able to create playlists or search by genre.

You might also like Tidal, if you're looking for royalty free music and don't mind paying $20/month for it.
