I would go to an aunt's house, and she would let me play music, and she had 'The Last Poets' album. At that time, albums didn't have explicit stickers on them, so some of the songs had profanity on them, and I was moved by that. I would listen to those songs, to the flow, and I'd balance it back and forth with the nursery stuff I had.
There were certain things that grabbed my interest, such as photosynthesis, such as us living off plants and plants living off us. You look at everything in that light - so if I'm looking at ice cubes, I might start thinking about absolute zero, or Fahrenheit and Celsius. There's so much that can make me think about science.
I think, as an artist, the overall goal is to teach and educate no matter what the song is about. Somewhere where a listener can get something out of it, something that can give them help to move forward, help them learn something, analyze something in a different way, or think about something.
