On Bono's 60th birthday 'Songs That Changed My Life' playlist, he has chosen 60 offerings of songs by other musicians that have offered him food for musical thought. Here, he thanks Daft Punk and Pharrell for their hit collaboration 'Get Lucky'.

The accompanying thank you note is addressed to each of them separately, thanking them for pushing the envelope and saying, "a song like this shouldn't be, but it is." You can read the rest of Bono's letters here: https://www.u2.com/news/title/60-songs-that-saved-my-life.
