Finding an email from an account [HELP]

Hello everyone. I last signed into one of my myspace accounts a while back, and the account im trying to sign into is to do with music (has thousands of views) and i just want to access it. I've logged into 2 of my accounts, and i only actually remember making 2.

But, is there a way to find an email account of a user? Like a scraper or something?

Thanks!
