Any music station recievable from Southend on an FM/AM/MW/LW radio?

Both MW and LW are AM type radio signals. There is no way to tell what signals you will receive as this depends on your exact location, the type of radio, the height of the aerial and even the weather. Just do it by trial and error. Unless you are interested in foreign stations (there are quite a few with a high proportion of music), then just concentrate on the FM stations.
