The OZ20 is a chart that combines streaming data from Spotify and airplay data from AirCheck to create a weekly top 20 of songs in Australia. In the formula, airplay spins are multiplied by 10 and Spotify streams are divided by 10. This isn't anything exact, but it basically means that, while streaming is dominant, radio support helps a song, and songs on streaming that don't have any radio won't do as well.
