I'm sure its an extremely well known piece, but could someone please tell me what the music is to a trailer on TV at the moment for Heroes of World War II? (I think thats what the series is called). Its on the channel called "Yesterday", they've been running a series of WWII programmes connected to the Holocaust and Nazi Sympathisers etc recently usually 9-10 pm. The music is haunting and beautiful and I'd love to know what it is and who its by!
I don't have that channel, so I can't answer your question directly, but there is a (free) web application "MusicBrainz" that lets you capture the music on your iPhone (or Android) equivalent, computes a digital signature from it, and from that looks up the title in a database, which it then sends back to you.
I think there are other Web services that do the same (like Apple's 'Lala') but MusicBrainz is the best known.
