For the course of the month, write down songs you hear on the "radio". Anything goes - AM, FM, XM, radio.garden, internet radio, twitch raves, cafe background music - EXCEPT any shows you have control over (e.g. stations you work for, your own sets, Youtube mixes [and other "sounds like X" mixes], etc.) should be disqualified. You're free to use either a variety of stations or just one. For extra credit, use only songs you hadn't heard before.
