Earlier today, my brother Ryan sent me this picture which is said to contain 72 musical artists. Without cheating, I challenged myself to find all 72. As you'll see from clicking that link, I've so far only named 62, and I'm pretty sure a few of my guesses are wrong.
Have a gander and leave me a comment if you can name one I haven't got yet or if you've found an error. To see my 62 guesses just hover your mouse over the notes.
Go!
