There are programs downloadable for DLing tracks off youtube if you care to look online.
And to get round area-specific blockades use TORbrowser, its a firefox derivative that integrates TOR, and you can simply route your connection through a server in another country in order to sidestep the block.
The one issue I've had with TORbrowser is that some sites, mostly academic, and OCCASIONALLY youtube, sees it as mass-access to the data, kinda like wardialling and systematically spidering for content due to the way TOR works (it bounces connections round multiple servers, assisting in anonymity. Especially if used with a VPN (since exit node traffic can be monitored with TOR still, or exploits by setting up bogus nodes to sniff traffic etc.) but you'd have to be up to something and attract attention beforehand for that to be worthwhile (E.g paedophile rings have been cracked despite their use of TOR)
But it will certainly get you round country-specific blockades, all you need do is change TOR circuit. Sometimes it takes a couple of re-routings for it to cycle to a country not affected by such a content block but it will do. Put the two together and DL what you want. Easy as.
