Need inspirational playlist for long runs !

3 weeks down still seeking sponsorship for Arthritis Research UK still following my Asics running app religiously for Great North run. Now just 3 months away. Can run 5.6 miles without crying or collapsing but app says I have to go to 8.5 this week. 90 mins for half marathon lifetime away!
I need inspiration. I need help to choose music playlist for long runs!
All advice welcome
