You could try the squeezebox or Sonos. I have a squeezebox duet, which comes with a remote, but you can also get a free squeezebox remote app from google market, it allows you to browse through the stations, and shows album art for the stations that support that feature . I love it. My favorite stations are BBC world service for news, Paradise radio,for music, I also listen to radio Caroline from England, and WXPN for my old home town Philadelphia. I also listen to a lot of podcasts. The squeezebox will also play your music collection from your PC. There are also a couple of paid ones that are supposed to be really good. I have the free android remote app, its OK, but I have a small cellphone, so I prefer the real remote.
Sonos is similar although I have no experience with it, but I heard its support for radio stations was not as good as the Squeezebox.
