How do I upgrade my existing iTunes purchases in my music library to remove DRM (Pre 2009)
My existing Music Library plays on my iPhone but will not play through my Sonos setup.
Songs are Grayed out. I see that some songs may not be downloaded on my device, which I understand need to be on my device if I am looking to stream to Sonos. I have been told that I need to upgrade my music library because of DRM, how do I do this through the iTunes store?
