There's a song that's stuck in my head right now. I've heard it in a DFS commercial (sofa store), I've heard it in 10 Years Younger when someone got transformed and had nice colourful clothes on and I heard it in Snog, Marry, Avoid? when some tarty girl was applying tons of fake tan.
The only lyrics I know in it so far are,"Get your colours on" The music in it sounds a bit like retro video game music.

I have never seen that advert but it's most probably Colours (the Seamus Haji Remix) by Calvin Harris ... man, I miss working at a music archive, loved the research.
Aha! I've found it! It's not the remix, just the original. :D Oh my god I'm so happy now I've found it ksjdfhkdjdkf;d Thank you thank you thank you!
