If you listen to music 16 hours a day, you’ll hear 107,815 average length songs in one year. If you keep up that pace for 90 years, you might succeed in hearing almost 10% of the music currently streaming. If you want to check out new releases, access other recordings, or listen to anything more than once along the way, in all likelihood you will hear less than 5% of all available music. For a quality 5% listening lifetime, you’re going to need quality guidance.
