This is for a UK based website, but they have tons of music for ballroom dancing. Some are just for Latin (jive) and some for standard (foxtrot, waltz) but I think there are a few with both. Some of the songs you can hear a sample of. Once you get the name of a cd you like, you can do a search and probably find someone in the US or Canada that carries the music. Some of the best ones that I have found are from Casa Musica. Enjoy your dancing!!
