I read the OP and sat here thinking, who the hell is the OP hanging about with. If you were listeing to Celine Dion then yeah I might question your musical taste (Im not into your taste as is but its yours so enjoy it) but I wouldnt start saying just becuase you listen to a female singer or a band with a female lead that its wrong.
My god how much great music I would have missed if that was my mind set. Really people who think like that really are not worth knowing or at least not untill they grow up a bit.
Yeah, it's like only liking paintings with green and yellow colour and ridicule the ones painted in red and blue.
