Yeah, bullcrap.
First of all, Tennessee Whiskey is about a guy crawling OUT of the bottle for the love of a woman. Looking for love in 'all the same old places' leaves the author with the realization that 'the bottom of the bottle's always dry'...
So it most certainly does NOT romanticize alcohol.
The same with the Brother's Ozbourne's 'Ain't My Fault'... The guy is all jacked up and in denial...
So the examples given are poor, though I could certainly point to better examples. But for every drinking song and party song you can find, you will also find songs about the danger therein, and many many songs pointing folks to right living and God. So the OP is wrought in shallow water.
