If China's ethnic replacement/relocation policy succeeds, as it currently is, Tibetans will meet the fate of America's native population - isolated in remote reservations and ghettoized on their own land.
If you have visited Dharamsala or any other place where Tibetan refugees live, you would have had the opportunity to hear modern Tibetan songs. The uncommon blend of traditional Tibetan tunes with a contemporary beat is particularly enjoyable. Although one is unable to grasp the lyrics, one can notice a word coming up again and again in all songs -- rangzen. It means 'independence' in Tibetan.
