Changing the pace a bit, I'd forgotten about voXXclub. (I'm pretty sure I haven't posted about them before - but not positive.) I saw one of their flashmob videos a year or more ago, but then totally spaced on it.
With that in mind, there are two videos below. The first is the flash mob, the second their music video. The flash mob video is very fun, and the music quality of the second is very good. However, the music video definitely makes me think of the 90s boy bands for some reason - so just bear that in mind. ;)
This song is just so happy.
