I find the whole thing incredibly depressing TBH. The days in which talent was the main requirement have long since gone. There has always been an element of charisma (or 'star quality') that could balance out a lack of a significant talent, but now it's pretty much all star quality. And for women that basically means - pretty to look at and prepared to gyrate half-naked on stage. For every Adele there are 50 Rihannas.
I don't allow my DC to watch music channels precisely because most of the videos are only a step away from soft porn. I don't think anything can be done about that until there is a significant backlash which demonstrates that people don't want to see it. There are whisperings of that already, but times change and things rarely go backwards. Popstars pulling scarves between their legs suggestively and swinging round poles are probably here to stay. What will mark the serious 'artistes' in future will be the conspicuous absence of any sex-related imagery in their music videos, specifically to grant them a certain gravitas. But sexualisation in pop is probably here to stay.
Bearing in mind the average age of pop music consumers, particularly the core fan-base in the 11-17 age range, I'd like to see music videos toned down significantly, and a social pressure on pop stars to recognise their demographics of their fan-base. Don't think it's likely though.
Rihanna once famously argued that she never wanted to be a role model - she was a performer. It was damaging her creativity to be forced into a role-model persona and it was unfair to criticise her for not conforming. I have some sympathy with that as an argument in principle, although for a manufactured pop icon whose fame is based mostly on massive sex appeal and aggressive marketing, my instinctive response to this argument in relation to Rihanna is "bollocks". Make her put on 3 stone in weight, wear a kaftan in all her videos and write all her own songs and I wonder how much fame her singing talent will continue to generate for her.
Despite all that, proscribing what performers can and cannot do - beyond the normal confines of legally defined taste and decency - is a form of censorship. And that's a bad thing IMO, no matter how well intentioned.
I'm under no illusions - I can probably only get away with restricting my own children's access to hyper-sexualised music videos and internet porn for another year or two before my strict controls over my children's media usage are undermined (if not annihilated) by access granted through friends' phones, etc. Not a lot I can do about that other than lock my children up in a bubble, which is arguably even more harmful. I've chosen to deal with it by talking to my DC about it all.
It's not just music videos and porn that we discuss, it encompasses feminism, capitalism, relationships. Intelligent parenting which encourages children to analyse what they're fed rather than accept it on face value can undo a lot of the damage. Children are remarkably intelligent and capable of seeing through the marketing BS a lot more than we give them credit for if we make it our jobs to give them the tools to do just that.
