Before you mark this question a duplicate, read the question properly.
I have had a domain `http://muzic.asia` and because of low quality TLD it's SEO rankings were less (For some keywords it ranked even to the first position in Google). see this img: [![danga maari mp3][1]][1] 
Since I learnt using a better Keyword & TLD in domain could boost the domain's SE visibility, I registered another domain: `http://fullsong.org`

I have learnt that a 301 permanent redirect could notify Search Engines about the domain change as suggested in hist post - http://webmasters.stackexchange.com/questions/21720/preserve-search-engine-rankings-while-shifting-to-new-domain-name 
But here the issue is like this - http://webmasters.stackexchange.com/questions/37973/rankings-dropping-after-small-url-change-with-301-redirect

Because most of the URL which are indexed in Google are like this:
`http://muzic.asia/music/view/10750720`
And I want to change the URL with the new domain as:
`http://fullsong.org/music/view/10750720?download=Goli-Maare-Tera-Dupatta`

So how do I redirect the domain. Should I redirect the domain only to the main page like `muzic.asia => fullsong.org` or redirect each URL to the new URL like 
`http://muzic.asia/music/view/10750720 => http://fullsong.org/music/view/10750720?download=Goli-Maare-Tera-Dupatta` or should I submit every new URL to Google again?

Note: I do not have access to the .htaccess
