What's in your top 25 most played songs on ipod/iphone?

Just wondering as i'm trying to start up my collection and need some ideas… Open to all types of music so give it a shot!

Underground Rap. I used to hate rap, but now all these rappers that make their own lyrics and beats. Its actually really good music. I still hate mainstream.
Suggestions:

Chris Webby
Hoodie Allen
Hopsin
