Depends.
Sometimes I just can't find the actual thing by legal means. Go try listening to Bruce Woolley's version of "Video Killed The Radio Star" sometime. I can either try to hunt down a physical copy or I can just pirate it. See also: most video game soundtracks.
Usually though it's more about convenience. If I can just stream something on Spotify, I'll just do that.
If there's a movie I kinda wanna see but I'm not sure if it's going to be good I'll pirate it
Based on your other comments of mentioning she was on the phone, it sounds like what was really bothering you was that the phone was getting attention and you weren't. So just say that.
You definitely need to get comfortable with having quiet time where you're both just reading, goofing off on the phone, or whatever. You can't talk 100 percent of the time.
If the actual silence is an issue just throw on some music. I can't think of a nicer time than starting the day with some coffee and music.
