Rhythmbox is a music management application, designed to work well under the GNOME desktop. In addition to music stored on your computer, it supports network shares, podcasts, radio streams, portable music devices (including phones), and internet music services such as Last.fm and Magnatune.
W.A.I.T. (What Am I Trading?) Rhythmbox allows and promotes trade-based radio stations, those who want users’ attention in return for letting them listen to their radio stations. However, Rhythmbox is more than that, it is a music player that can be used to listen to local music.
