Making taubah for making nasheed CD's with music

Q: If many years ago (sometimes before bulugh and sometime after) if one used to make a CD for family members so they could use the CDs in their cars and the CDs would have nasheeds on them (mostly with music but not all), and if at least with one relative he used to try to get something out doing so i.e. being taken to a store to buy a magazine.

The way he made these CDs were by downloading a YouTube video to mp3 file (which YouTube would have been against) and then putting the mp3 file on a CD.

Now, would he have to find those naat and nasheed artists and owe/pay them any money, especially those artists who didn’t use music?

Interacting with a murtad

Q: I have a relative that turned to Christianity. He therefore is a murtad for more than 30 years and I refuse to associate with him. Some family members however associate with him as per normal. I even saw him recently in a masjid for his mother's janaaza taking part in the salaah.

I would appreciate if you can advise as everyone thinks I'm at fault as I must greet and interact with him to show him the beauty of Islam although he is a born Muslim. We tried in the beginning but he regrettably still practices Christianity.
