Roll up, roll up! Welcome, one and all, to our Top 5 Videos of the Week – some stellar, and somewhat baffling, picks this week: from Willis Earl Beal's lost Church Or Nobody tapes (starring Mischa Barton) to Katy Perry's 'illuminati-themed' clip for 'Dark Horse'. Also featuring are London Grammar, Shivum Sharma, and the return of Samaris.

We've tried to make it easier for you to enjoy our weekly roundup by putting all the videos into one handy playlist. You can still pick and choose which video to watch, but if you fancy watching our favourite videos back-to-back, this is the best way to do it!

We recommend selecting the HD option, making it fullscreen and relaxing in a comfy chair.
