Three singers collaborate with Siri to make an awesome music mash-up

It can read your emails, it can tell you what the weather's going to be - but did you know that Siri can lay down a pretty good beat?

During what appears to be (but just really isn't) a study session, a student asks Siri "What is one trillion to the tenth power?" - which is one with a lot of zeros.

As Siri begins her arduous task of rattling through the 0s, things get a bit more... interesting.
