If you want a new console + a PC at your TV, I think the new Steam Machine could be nice for that.

Running SteamOS (Linux) this should be good, or am I missing something?

Depends on who you are.

If you often discover music and searches for songs, your method is not the experience prefered.

If you always listen to your playlists, and sometimes want to add a new one, yours work great.

What everyone really wants, is a player that autodownloads and plays while downloadning, like with torrents, and then gives the option to auto remove after x days or keep forever. Everything happening under the hood.

Otherwise I’m afraid it will keep away most people.
