I found this site called Incredibox randomly and love it! The description of the app itself is "Express your musicality, pump it up and chill! Between creation and entertainment, Incredibox invites you to become the conductor of a group of human beatbox." Who wouldn't love that? You can make your own random music with different effects, beats, melodies, choruses, and voices - just drag them onto the man and make a 10 note song! For some reason, any combination of sounds I put together sounds good. Play around with this app and enjoy the crack-like effects this site has ha!
