This article is pretty silly.

- Spotify is primarily for streaming Spotify songs. It shouldn't be inefficient, of course, but you're looking in the wrong place if you just want to play your audio files.

- Groove: Windows built-in programs are rarely great, why expect otherwise from Groove?

- Come on, dude. You can't just write something off because the homepage has a trendy design. And Shoutcast is ancient technology! I'm pretty sure I used Winamp with Shoutcast on my Pentium 4 and it worked fine.

- Foobar2000 has been around forever! It was fast and efficient ten years ago, and that hasn't changed.

This guy should have done a little more research.
