They do have a desktop client, however it has a well incompatibility with newer versions of libgcrypt on recent debian/ubuntu. They don't seem to care about fixing it. Plus, the desktop apps, on my laptop, spawns like 7 SpotifyHelper process that take hundreds of mb of ram, which out of 2gb is pretty significant. Still better than the flash-based web app which doesn't even play without cutting out.
