I have two questions:
Does changing file names have any effect on the fields? Since I want to repeat the same field several times in my playlist, I put numbers to the file names. Its how my portable player works. Will changing file names affect the effectiveness of the fields?
Can I have my sister and my mother play the fields from Patreon and Gumroad? I am the member of the Patreon and I bought from Gumroad.
Thank you in advance.
yes this is fine as long as you don’t change the actual audio
You can share gumroad audios with your close family and the patreon can be shared with anyone, unless it is the premium subscription. anything from patreon works even when you end subscription too. (unless it is premium audios)
i’m sorry for another question but just to be sure is it also okay to copy/send files through apps for sharing between different devices or should i directly download them from gumroad each time? i know it’s probably not how protection works but still… 
It’s okay to do that i belive. i’ve been doing that
As long as the file is originally sourced from gumroad it is doesnt matter where it is moved
just dont run it through audio editing softwares and resave.
thank you 
got it!
Thank you for your letting me know.
Apologies for the late response.
My membership is “Full YouTube Audios Access”, probably this is below premium. For the audios to work after ending subscription I must be premium member? Do I even need to replace my files with files downloaded after upgrading to premium?
If you end your the Full YouTube Audios Access subscription the audios will still work.
the premium subscription has exclusive audios, different to your subscription, that stop working once the premium subscription ends. think of the premium as renting the audios and your one as buying them permanently.
I see. Thank you so much for letting me know!
no prob
