OP, here's an idea outside the box: For just a moment you might want to think about an alternative to Spotify, like a subscription to Apple Music which you can enjoy from iTunes downloaded to your PC. Your amp features Airplay so you'll be able to instantly enjoy Apple Music streams from your iTunes Library to your amp wirelessly. And, the iTunes and Remote apps installed on your smart phones will permit access to Apple Music streams from your library anywhere on the Planet. With Apple Music you also get music recommendations, browsing, radio, and iTunes Store integration all synced to your iTunes Library app. Finally, iTunes allows playlist creation, CD ripping, and CD creation. The bottom line is Apple Music/iTunes is BOSS, period. And I've gotta tell ya, the sound quality of Apple Music streams and downloads rival the 24/192 music I have in my iTunes Library. You can download iTunes for free and you can try out Apple Music for 90 days for free, if you decide you like it the service it's only $9.99 monthly, allowing unlimited downloading of virtually any recorded music in the history of recorded music. This music does not need to take much space on your computer either since it can all be accessed from iCloud. Apple Music delivered by iTunes app. is the Daddy.
