A recent search on Amazon turned up two new producers of commercial music for your listening pleasure, including a large dose of “screaming chorus, thundering orchestra” albums, better known as modern film trailer music.
Try Northbrook Film Collective for fifteen mp3 albums and West One Music for fifty(!) mp3 albums. Of course,at West One Music’s website you will see they have some two hundred albums(!!) available to corporate clients, some of which hide at Amazon under a West One Music search results.
Crank up the computer speakers, pop in the headphones, these can keep you busy listening for quite a while, if you’re so inclined.
