What are some of your essentional gameplay mods?

MCCC; Road to Fame: cool-down between song licensing; SNB; SNB-Bills; and a few random custom content stuff. I'm also exploring a mod that allows for more students, that your active Sim can choose. We'll see if my other family in the game will attend high school. I don't mind if I can't control them at that time, but I wanted my up and coming Rock star to meet his forever mate in high school.
