Skins and plug-ins are available for quite a few players, but the majority are designed for the WinAmp MP3 player. Although music gets the lion's share of attention, there's a wealth of spoken word content on the web. Audio books have been around in cassette and CD form for a while, and now you can listen to books online. Excerpts or complete texts of audio books are available in streaming audio. Many texts are free and a few sites let you download whole audio books for less than the cost of buying the CD or tape.
More literature is accessible in the form of audio dramas or poetry readings.
Radio plays have gone digital with both new interpretations of classics like Shakespeare and new original productions. Poets of all description can be heard over the internet from old recordings of T.S. Eliot to modern rebels like Henry Rollins. Educational and informational audio is also abundant. You can take language lessons, listen to lectures from universities or take in speeches from famous personalities. Audio programming about health, fitness, business, technology, news and travel is readily available from various sites.
