I don't get it. How does she get so much attention? How does she win so many awards? Industry politics? Her whining?
She's famous for getting used and then dumped by a bunch of A-list celebrities and then writing generic songs about it. Extracting semen from actors who then split seems an ignominious legacy.
She gets attention for being a talented song writer and a skilled performer. Her being beautiful probably helped her get where she is. As far as people beyond teen females listening to her music-- I work as a wedding and corporate party DJ, and know with near certainty that if I play a Taylor Swift song, most guests will dance, and the energy in the room will increase. I see men and women from teen to 70+ smiling and dancing to her songs. I don't know how often they listen in their spare time, but they certainly recognize her music, and will come to the dance floor when her music is played.
I don't know her that well. If the song doesn't repeat the word "never" I don't think I would know it was TF, and I kinda like her, at least for her looks.
You've clearly never seen a DJ perform if you think the DJ can play any song and keep people dancing. It's especially difficult at something like a wedding or company gathering, where one musical misstep can alienate the crowd and kill the dance floor for good.
