Radiooooo.com is a new, *free* online service that allows you to travel through time and space to discover music. Users have the ability to suggest music to the site editors and further build its vast catalog of tunes dating back to 1900. It’s pretty incredible—you just click on any country, select a decade, and decide your “mood” (slow/fast/weird), and all of a sudden you’re listening to Azerbaijani music from the ’50s (which is great, by the way). So far my favorite stumbled-upon jam is Syntoma’s “No Me Puedo Controlar,” which I got after picking “weird” music from Mexico in the ’80s. I now know that Norwegian psych from the ’60s isn’t my thing. Enjoy—this is like having a time traveling jukebox live in your computer.
