I agree. Rappers do mixtapes all the time sure, but it's very rare for a Pop girl of Miley's statue nonetheless who's supposed to be this controlled, calculated person with no mind of her own to simply release something for the pleasure of her fans for free on Soundcloud
Like you said she isn't making any excuses and doesn't have any hidden agenda. She made something she truly believes in and that is admirable whether you like the album or not
I havent listened to it yet, but I kind of am interested in what she will do with her next album. There is something wonderfully unapologetic and rebelious about her.
