Please help me pick a Roku

Hello, I need a little help. I'll start out with describing my needs.

I do not watch any current TV shows with one exception: Archer. Besides that, the only other thing I watch is the Barclays Premier league and the UEFA Champions league. Why do I want a Roku? For the following reasons:

  1. To stream Spotify directly to my speakers without the need to have my TV on. Roku has an Android app, can I choose the song I want to play right from the app on my phone? Can I move between playlists?
  2. To watch the occasional Dexter's Lab and Top gear on Netflix. Also, can the Roku stream live sports? Or maybe that's not the point of it. I'm not really sure.
That's pretty all I want and need it to do. Help?
