I bumped into a new site that combines video, bios and lyrics (when available), designed by a Spanish guy from Tarragona. It is called esfresh.com. You can create different playlists as in radioblogclub.com, but with videos.
I have started one for my students with videos of the songs we have already listened to in the classroom or the ones I'm preparing now. The good thing is that they can watch the video while reading the words if they click on lyrics. Here is another playlist with videos of Salsa music. Some are quite old, but curious. And the last one for French and Italian music.
