I just opened this ticket on Spotify forums suggesting that need to support the efforts of Volumio team: community.spotify.com/t5/Spotif … i-p/994067
Vote it up if you like, and share it on the blog for the users to vote. Some may not be able to contribute money, but what everybody can do is to click on the link and vote this up.
Btw, great job with Volume 1.5. I am amazed by the sound quality I get out of Spotify. Very neat.
