YouTube has become a go-to music player, but its one-song-at-a-time format doesn’t make for a seamless listening experience. Tomas Isdal, a Ph.D. student at the University of Washington, has changed that with Tubeify, a mashup of YouTube, last.fm, and Billboard that acts like a jukebox: plug in the name of an artist, album, or song, and last.fm will deliver a playlist of YouTube results for immediate listening, or to be saved for later. There’s also the “Top Charts with Time Travel” feature powered by Billboard, which allows you to listen to top tracks back to 1964. (via: The New Yorker)
