My Mother listens to music constantly?

So over the last month or so, I introduced my Mother to Queens of the Stone Age and dessert rock, she immediately loved it and she's been obsessed with it since. She litterally listens to it all day, it's becoming unhealthy. All she talks about it Josh Homme ( the lead singer/guitarist of QOTSA ) and she's been acting very differently. She wants to get tattoos now, and she really wants to vandalize hotel walls cause I guess that's something that Josh does. She litterally listens all day, and if I try to get her to take her headphones out to tell her something, she gets very angry. Is this something I should be more worried about?
