Online radio that allow to choose mood of music.

Musicovery is an interactive and customised webradio service. Listeners rate
songs, resulting in a personalized programme. Reviewers have commented that
unlike services that are governed by the user's choice of artist or genre,
this method results in more discovery of artists to which the user might not
otherwise have been exposed.
Musicovery provides dance mix - with the ability to specify the desired dance
tempo - and similar artist features, as well as the option of a low fidelity
free service or a premium service with better sound. Users have the option to
limit the selection to a specific year or range of years, as well as to
deselect any genre, and genres are color-keyed to the graphic interface.
