&gt; A couple of years ago Spotify rewrote their clients to use CEF<p>Eh. And not to sound like a cranky old man, but that shit sucks.<p>It&#x27;s ridiculous that their &quot;app&quot; needs 20-30 seconds to boot on a modern computer. It&#x27;s a damned music player. Plus, when the machine is under load, it skips like a 1993 disc player. And the damned thing crashes routinely.<p>Pre-CEF I was terribly impressed by their mac client. It&#x27;s been a pretty ugly cliff they&#x27;ve fallen off though. They did a developer blog post some time ago detailing how teams are all using separate JS routines and libs... and I have to say, I wasn&#x27;t surprised. It&#x27;s rare that a popular app regresses in performance and usability quite as much as they have.
