Synths, beautiful sound, diverse qualities, but nonetheless it's all quite great.
It started with movies like John Carpenter as he made his own music most of the time and disco like themes such as Scarface "Push it to the limit" even before that like sounds from Pink floyd synths, to Kraftwerk and many, many, many more. Now we have a New Wave of Synth like Daft Punk they have a great sound but there is more, but I forgot how to youtube this
