If you’re looking to update your music library, here’s an interesting way to do it. This site lets you listen to five seconds of every number one song in chart history until 1992. Separated into two parts, the songs are played one after the other in a remix type format and it’s actually quite fun to listen to. Kind of like those annual remixes of the top pop hits from the last year, but on a much larger scale. tinyurl.com/6glvfxb
