Artist Index

I am currently creating an Artist Index for the left hand side of my contents page - similar to NME.
Here is the A-Z of artists that will be included:

Adele
Amy Winehouse
Ben Francis
Beyonce
Carole King
Charlie Simpson
Damien Rice
Demi Lovato
Ed Sheeran
Etta James
Florence Welch
Grace Hill
Gotye
Jessie J
John Mayer
Kate Nash
Kelly Clarkson
Lady Gaga
Lil Wayne
Madonna
M.I.A
Nina Simone
Noel Gallagher
Paolo Nutini
Prince
Rihanna
Robin Thicke
Sam Cooke
Sia
Taylor Swift
Whitney Houston

As you can see, these artists vary in genre and this is because one of the main things I wanted my magazine to do, was to be a range of different styles of music to create a wider audience interest.
Currently, the list does not take up the full side of the page as I was hoping. I will either make the text bigger to fill the gap, or I will add extra names to the list.
