I know many people who listen everything but radio music. I rarely listen radio, unless is a rock station. And I actually watch a lot of Видео on youtube. Surely I'm not the only one. Maybe radio comes in handy to some people или maybe they like that Музыка that's been aired in continuous loops over and over again.
Maybe not everyone has heard of Vevo или I don't know other ways. Besides, how do Ты know these people Ты talk about only listen to the radio. There are a lot of people. Like myself, I rarely ever listen to the radio, sometimes when my sister is only on the air, I also rarely listen to Музыка on the internet though. I usually just listen to what's on my ipod. And as for these other people, who knows.
I only listen on the internet, или download the MP3 and listen to it on my phone или Foobar. I am guessing because they don't know what to listen to so they listen to the radio. I mean....I would do it that way if I liked hearing Музыка constantly.
