AAaaaah I love listening to quality chill, off the top of my head there's a couple of tracks that spring to mind: 
  
Ott - Smoked Glass and Chrome - You see, usually I can't stand women warbling vocals in tunes, but this track is devine.  Sooo beautiful, top notch, can't wait for the next ott offering  
  
Nada - Raji Mati  MMMMMMMMMMmmm nada!  I think butterfly dawn was my first ever nada-experience, and again another beautiful track!  I am now a liquid sound design convert, love all their releases, but nada are definately my fave. 
  
Ooze - Quintessence  What happened to OOze?  I love this track, in fact I love the whole album, but this one is fab.  Happy memories of driving down the highway in Aus post-doof with a bit of OOze blasting   
  
There's loads more that make me go 'MMMMMMMMMMmmmmm' but that'll do for now
