Ok, I am not much for sharing links to videos, and, in fact, rarely click them if someone else shares them, but I really enjoyed this song:
A Capella Science - Bohemian Gravity!, and decided to mention it on the off chance that some of you haven't heard it elsewhere. The boy has a lovely voice and a good hand with a mixer to combine his many harmonies with his melody, I have just enough understanding of hard science to appreciate (if not always follow the details of) the lyrics, and they are done well enough that if one wasn't paying attention one might suppose that it was the original song being sung, rather than a clever filk.
