National Eight Track Tape Day (April 11) may bring you back to the days of shoeboxes filled with the large cassettes and that funny hiss they made in the players. The next generation of music formats, cassette tapes, ushered in the mixtape, a DIY playlist to treasure and gift. Head on over to Kaseta to make your virtual mixtape for free.

Mixtapes are all about discovering new music from others. If you need some musical inspiration, check out Music-Map, a site where you enter your favorite artist to see an interactive diagram of other artists you may enjoy. Music-Map is part of Gnod, “the global network of discovery.” Gnod also helps you discover movies, art, books and more.
