iPad Air - How many GB do I need?

[G109189]

I am in the market to purchase my first tablet and after doing research on which I wanted I decided on the iPad air. I am unsure of how many GB I need and would like some advice. On the tablet I intend on storing some, but not all of my music and maybe rotate some TV shows every now and then. I am also a comic book fan and wanted to purchase some comics through the DC and Marvel apps. I should also mention that I do not play many games and any apps that I download will likely be Netflix, Social Media or sports related. Any advice or help that you can provide would be greatly appreciated. Thanks!
Should clarify that when I say "some" music I mean roughly between 5-8GB
