Description of your pull request and other information

Like #7514, this commit makes downloading mp3 from netease possible again, by using hostnames that resolve to CNAMEs on CDN.

Should I revert 75af5d59ae5c4c6549cce5357a8a8d060c3f462c to enable the tests?

This does not seem to work at all:

@dstftw Thanks for your quick response. I have fixed xrange.

Yea your case fails on my end too. But it seems that http://music.163.com/#/song?id=32102397 is a piece of music behind paywall, thus it doesn't surprise me when http://music.163.com/api/song/detail?ids=[32102397] returns me None for the key ['songs'][0]['mp3Url']. I can't make magic out of that.

My (smoke) test cases (done on zsh) were:

• http://music.163.com/#/album?id=3317645
• http://music.163.com/#/song?id=423406359

And yes, I am actually able to download them.

Could you try some free ones?

Test should be revisited and skip removed for those that work with this approach.

[dstftw]

Squash commits when done.

[caizixian]

Per code of you-get, adding '/'.join(info.get('mp3Url').split('/')[0:3]) and "http://p{}".format(info.get('mp3Url').split('/')[2][1:]) to hosts list might help. Need more feedbacks, so no new Pull Request atm.
