In an interview backstage at a concert in Hollywood, Linda Perry tore into Katy Perry pretty brutally, claiming that it's music like hers that has led the music industry to "turmoil."
In the interview, Linda candidly admits that she understands the appeal of Katy's music, but insists that there is no "substance" to it. While she concedes that Katy is "great for what she does," she insists that the Teenage Dream album is "crap … sounds like ****," and that's why people are only buying singles and not the album itself.
Linda further put forth that she didn't think Katy was interested in "changing the world musically," otherwise she would be making music that wasn't just "microwave popcorn for you to feed on." She added that even though she wasn't the hugest fan, she is more inclined to praise the career of Adele, who created a "solid" album that was superior musically.
The issue with Katy's songs isn't that they have no substance, it's that for the most part they're bad, uninteresting songs with no substance. At least IMO.
hahahaha this girl! She really isn't afraid to voice her opinion.
She is right though, Adele's record ***** on Katy sales wise and substance wise.
But she also right about Katy being great at what she does witch is making fun/pop music.
Katy didn't start a trend with it
