Songs for 'Of Mice and Men' assignment?

[Cookiettt]

I need songs for an assignment on the following themes or events that could go well in 'Of Mice and Men':
1 - Loneliness
2 - Dreams (ambitions)
3 - Pessimism and Optimism
4 - Racial prejudice
5 - Friendship
6 - Killing someone by accident
7 - Your only friend dying

Thanks so much
p.s. I have been searching for songs but none of them fit well enough
