MOSKVA.FM is the best resource I’ve found for listening to Russian radio online. Stream popular radio stations (Эхо Москвы, Наше радио, Русское радио, and many more), listen to archived programs (news, horoscopes, countdowns), and browse the charts (хит-парады). The interface is what really sets MOSKVA.FM apart: it shows what song is playing, a box for user comments, and a visual timeline of the songs and programs that have aired – it even notes each song’s number of rotations. Also, click “текст песни” to bring up lyrics in the window as a song plays. More features are available for registered users (including the ability to make playlists).
