Title : The world's biggest spiders

Hi there. The link doesn't work~unless you take the word 'watch' out of it... found it and I don't know that name of the song... but if you go to the guy's page (the one that uploaded the video) and send him a PM and ask him I'm sure he'd tell you. You'll need a YT acct. of your own to be able to message him or comment anywhere.
Here's a link to his channel. Good luck.
