ROCKS! I had been using 2 keyboards and 2 tragic macpads to control my MB Air and MacPro, now I can seamlessly control both from the Air. THANKS! (both machines running Lion)

Kind of an audiophile here, external dac (apogeee), headphone amp (cute beyond with upgraded op amps, fave phones Grado, Ultrasone if you need closed). Have tried Cog, Vox, Songbird (do we really need to mention iTunes - what's the deal with the gritty dark compressed sound, I thought Steve was a stickler for quality?). The interface is kind of kludgy but the sound quality breathes like no other player. If you're into sound quality nothing else will live up to Play. I hope it stays compatible with Mac OS whatever for a long time because I can't go back to anything else.
