A rant about boy bands

One thing I don't understand here is the boy bands. Generally boy bands do not write their own material, nor to they play any instruments. Their purpose, as far as I can see is to get several men (or boys) together and then use them to market the hell out of everything. To this end, your boy band members should be as young as possible so that you can get as much mileage out of them as possible before they succumb to the Alec Baldwin syndrome. (Hot for about 5 minutes and then they become old men with beer bellies). Their requirements logically, should be to be as good-looking as possible and be able to dance. Occasionally, they might also have decent voices although this is largely secondary.

So what I don't get are the Taiwanese boy bands where many of them are comprised primarily of older men most of whom are not particularly attractive. Furthermore, most of them can't dance. I guess maybe they can sing, but when 5 people are singing it's sort of hard to tell. These bands seem to me to be really missing the point of the boy band phenomenon. On the other hand, Korean boy bands, or rather the one that has released a CD since I've been here seem to get the point, all those guys clearly have had some plastic surgery and they just show lots of close ups of their faces, also they can dance very well.
