She makes pop music. Popular music which is intended for a certain audience. Just like Justin Beiber only appeals to certain people Lady Gaga is exactly the same. She is mainstream pop, just like Britney Spears and Madonna before her. If you aren't keen on that type of music then of course it wont appeal to you - likewise if Gaga is your thing then it's doubtful you would think the likes of Joni Mitchell, Sam Cooke or Mozart are masters. Chances are that if you don't like what she is doing then that type of music never has and never will appeal to you.
Horses for motherfuckin' courses.
I like some of Lady Gaga's stuff, I also like Joni Mitchell, Grieg, James Taylor, Big Mama Thornton, ELO, Debussy, Bob Dylan, kd lang, the Red Hot Chili Peppers, Imelda May, Def Leppard, Sly and the Family Stone and a whole fuck load of other fucking stuff.
And I'll tell you, HappyBoi, another thing - HickBoy is no music snob either - he just doesn't happen to like Gaga.
Though he did share a plane with her once - or at least I assume it was his flight she was on that time I saw her in Dublin airport early one Sunday morning while I was waiting to collect him. He came out just 5 or 10 minutes behind her. She was there to play Oxygen 2009, iirc - at that time I had no freaking idea who she was, I just heard others around me saying 'Lady Gaga'. She was all dark glasses and a massive black headband - but from what I could see I thought she was reasonably pretty.
