It has taken me many hours to figure out from intense Googling that the reason Sonos won’t include certain songs from my itunes playlists is that these particular songs are protected (m4p). I have been all over the internet looking for a free tool to convert them. I already own these songs...I don’t think I should have to pay more $ to convert them. I don’t have very many songs with this issue.
Can you help?
Thanks in advance.

I sent you this information in a DM regarding another topic, but I’ll post here for full visibility as it may help other users:
In the past, iTunes purchased music was copy-protected using a form of Digital Rights Management (DRM) called FairPlay, and was not playable on non-Apple devices, including Sonos.
Apple no longer sells DRM protected music, and all music now for sale is free of any playback restrictions. If you still have some tracks that are DRM protected and unplayable on Sonos, iTunes Match allows you to upgrade your music to a DRM-free version. More information on iTunes Match and instructions on upgrading to DRM-free can be found on Apple’s website.
