Another amazing, stupendous, exciting edition of your Friday music round-up

(CBS News) It's time for another amazing, always stupendous and very exciting edition of your weekly Friday music round-up here at The Feed! Perhaps a bit too much build-up? Oh, well.

To start things off: do you have a love of all things Batman, but wish the theme music had a bit more edge to it? Well, fret no more, as we've got the cure to what ails you in the video above. The metal (yeah, that's right) kicks in hard at about 50 seconds into the clip. Check it out. 

The fast and furious rendition of the classic Dark Knight theme music was done by YouTube user ArtificialFear, who has really managed to capture a harder edge to the iconic sound while maintaining the integrity of the original song in this wonderful tribute. Well done, ArtificialFear!

Next up is some music in honor of those who might be feeling a bit down today. For those who just can't help but see a glass half-empty at the moment when it's obviously half-full. For those amongst you who might have some worries in their life right now... and to them I say, don't worry, be happy! Take a listen.

The endearing a cappella rendition of Bobby McFerrin's classic 1980's hit song "Don't Worry Be Happy" was performed by The Orthobox using a loopstation app on his iPhone, and should help put a smile on all of your faces. And if that doesn't work, remember that the weekend is right around the corner, people!

And finally, I've mentioned before that I have a soft spot in my heart for a certain band by the name of Passion Pit, and so I feel compelled to show them some love by including their latest music video for "I'll Be Alright". I hope you all enjoy them as much as I do, and would like to wish everyone a wonderful upcoming weekend.  And definitely make sure to keep coming back to The Feed for all of your viral video needs!
