The media does indeed love these drugged out, boozer celebrities. Gives them something to write/report about.
fe. remember Winehouse's breakthrough song? It might as well have been called "I'm comfrotable with my alcohol addiction". When she first surfaced, I felt 'rehab' was a run of the mill song. Nothing special, average singer. The media pounced on her, precisely because she was promising juicy stories down the line.
And now, there's Lana Del Rey ... again, Video games is an ok song ... but nothing exceptional. Born to die is even less noteworthy. But, again, she sounds drunk, she looks drunk, stoned or both. Media goes "if we hype this one ... loads of scandalous stories assured!"
Sex is too abundantly available. Sex doesn't sell anymore. Human car wreck stories sell.
