I discovered the free Spotify Playlist Analyser by Chosic today (no log-in required), and it’s an amazing tool. I instantly paid them $25 in thanks for creating it.
Every month I listen to ~1,500 new songs and had no way to keep track of them until I found Chosic. By listening to 18,000 new songs a year, I’m able to cover just about the entire listenable musical universe, I think.
Sure there are hundreds of thousands of new songs recorded every year (especially in recent years), but how many are worth listening to? One percent of 1,800,000 songs is 18,000 songs and I listen to that many every year so I’m probably not missing anything.
