This, as howtheduck surmised when analyzing a recent Lynnsight, must be based on her using all these musicians as a back-handed way of getting back at her brother Alan for some perceived slight. The message that she seemed to be trying to convey is that she used music as a means to calm herself down after dealing with her mother. When she was playing music, she wasn't mad at her father or brother and seemed to sharing the love of music that he and she had and that her mother did not as a means of getting closer to him.
Where things all seemed to go wrong was that, well, Alan made a go of being a professional musician and, in her eyes, won the battle that existed only in her bellicose brain. Since Alan 'stole' her sole means of getting close to her father and fending off the lack of interest her mother showed in her own endeavors, she'd soured on playing music. She'll listen to the genres she likes but since it no longer serves any purpose meaningful to her, she doesn't play music and doesn't like the professional musicians who want her to be miserable.
