My mom hates Lady Gaga and doesn't want me to listen to her anymore.?

I was just playing Bad Romance on my violin when my mom told me to
practice, and then she started yelling at me for playing such "bad
music" by an artist that is... a bunch of swear words, apparently. I
went back to playing the usual classical music, but then during my
free time, I started to learn Edge of Glory, and I had it playing on
my iPod. She came in and started screaming at me, again, asking,
didn't I hear her the first time. Now, she took my iPod and deleted
all of her songs, and now she's moderating all the songs I'm listening
to, making sure there is no Lady Gaga anymore. I love Lady Gaga so
much, though, especially her knew album. I've tried explaining to my
mom how inspirational the Born this Way album is, but my mom won't
listen. How else can I convince her to let me listen to Lady Gaga?
Lady Gaga is not stupid. She is so much better than Justin Bieber, and
the two of them shouldn't even be paired together. I don't want to
hear about how some people dislike Lady Gaga. I want to know how to
convince my mother to at least let me listen to her.
