Music channels (Media consumption over 48 hours)

Monday afternoon, after sixth form i ventured back to Emma Cleary's house as she was ill and i thought i'd pop in to see her. I also had to find somewhere to wait as my mum was picking me up and she wouldnt finish work for a couple of hours so thats actually the main reason, i just have to make sure Emma does not see this. If i come in with my face ripped off...she's seen it. anyway after an hour or so she needed to go to the doctors and i was allowed to sit back relax and watch a bit of telly in her household as Emma and her mum went to get told that Emmas 'fatal illness' that she made it out to be was in fact, a cold. As she was out i thought i may indulge myself in the music channels. naturally being channels dedicated to music i would say 80% of the advertisements shown were related to music. The other 20% were taken up by the likes of Febreze and Lenor. Also another i noticed was that almost all music videos had a half naked woman within it. The reason for this still eludes me, im not complaining though, i personally think its fantastic. im a teenage boy what do you expect? However im intrigued to know why music companies feel the need to demonstrate such sexualisation with their videos. I think the videos should be about the music and not about how scrumptious the women are within the video itself. Also why is it always women in the videos, i feel a few more half naked men within the music channels could balance out the preferances of both men and women, lady gaga i noticed has been trying to do this but more artists should be compelled to contribute in this cause. If anyone understands as to why people dressed in minimal clothing is essential for a good music video please let me know.
