A member of spotify team said to separate the FLAC idea post, into FLAC local playback and FLAC streaming. Someone else can create a FLAC streaming post, as I'm only after local playback. The original post with the 2 ideas in one post is here.
Vote for this post if you want LOCAL PLAYBACK OF FLAC FILES ONLY.
WHY WE NEED SPOTIFY TO PLAY OUR FLAC COLLECTION
Spotify already plays ALAC, all be it with stability problems, but what we really need is local FLAC playback because FLAC is the defacto standard for lossless audio encoding. 7digital has recently started selling FLAC yet spotify can't play them. Why not???
The most commercially successful band on the planet (The Beatles), have released official remastered versions of all albums in 24bitFLAC format on a usb device.
Numerous bands have sold albums in FLAC format through their websites. FLAC is the defacto standard for lossless encoding, so please start supporting local playback of FLAC.
Another idea that is important to me is fixing the appalling "set the same volume level for all tracks", which doesn't take into account the subtle volume transients of an album that audio engineers spend hours working on. The following volume normalization method retains the intended volume differences as part of the album.

Thanks to everyone for their contribution to this thread. We really appreciate it. In the interest of full disclosure, we’d like to share with you the status of this request.
This was a popular request, so we thought long and hard about it. However, we’ve taken the decision not to pursue FLAC playback as we believe the time and effort it would take to implement such a fundamental change would be better spent developing other areas of the service. As a result, we’ve marked this idea as “Case Closed”.
We appreciate your understanding and hope you’ll agree that some of the cool features we’re currently working on will vindicate our decision. Please keep those ideas and requests coming! Together we can make Spotify the best it can be.
