How Can I send you a submission for the intro music?

Hello, long time listener and plus member here. Love the show, and always really dug the Intro music back when i first started listening. I dreamed of recording a song to send you, but I didn't have gear or experience at the time. Fast forward 9 years and I am hoping to email you my rendition of the intro music but don't know where to start. Can you help me out?
