Sounds like Avril has made a few enemies!
However - there can be two sides...
If she genuinely thought Micca & Khatt were father & daughter then she made an honest mistake - Micca is a lovely friendly bloke & maybe she was misreading his signals.
What are the specific pop songs that are being dismissed as worthless? Are they REALLY the dross type, or just not suitable to a particular style of club. There are good and bad songs in "pop".
There are plenty of threads debating the issue of whether or not it is acceptable to read the words - and there are arguments on both sides.
I don't know Avril - but I hate to see anyone being so completely slagged off.... - especially when she has given her name and location & so has made herself vulnerable to attack
