Antwoord op "Audio glitches in apps like Spotify, YouTube, Google play"yea I believe it has something to do with the software. A workaround to avoid the audio glitches is to download Spotify to MP3 and transfer them onto your phone for offline listening. This way you can get around with the Spotify app.
Antwoord op "Spotify on an old iPod?"Spotify does not support music streaming on iPod Nano, Classic, or Shuffle. I‘ve read a post in the Spotify Community, saying that some old generations of iPod Touch can install the old Spotify app which stopped updating. Not sure whether this method is available for iPod Nano. Apologies that I cannot find that post now. https://www.audfree.com/spotify/sync-spotify-to-ipod.html This article here might be helpful to you. I use the Audfree music converter for Mac to download Spotify songs and then sync them to my iPod Classic.
