A very prolific singer/songwriter and savvy businesswoman who writes catchy, inoffensive pop music with lyrics geared to her target audience of mostly white teen girls and young women, and who actively cultivates a parasocial relationship with her fans. Her music is not for me, but she does what she does exceptionally well. I think I haven't seen a fanbase so huge, so dedicated, so obsessed, and so mad about a singer since early Madonna times.
