FM Radio
In every Uber and/or cab I end up taking, I ask them to turn the FM radio off.
The jazz and classical stations are okay, but then the commercials completely ruin the listening experience - especially for 'chill out' genres like the above.
Word of mouth from friends - Spotify or Apple Music playlists, these are great ways to find new music. What's on popular radio stations generally just annoys my friends and I.
Between the terrible selection of music, spotty audio quality, and ads, there's never been a worse time to pick radio.
You can also find it on I <3 Radio.
