Users can upload their films and videos to the site and run tracks beside them, to get a feel for what works. It hosts more than 1,500 current and upcoming music tracks including pop, R'n'B, dance, rock and classical.
Access is at BMG's website, where creatives can register on the "music for ads, TV and film" section. Tracks can then be ordered online.
BMG provided the soundtrack to the Nike World Cup ad, JXL's remix of 'A Little Less Conversation' by Elvis Presley, which later became a number one hit.
It has also provided soundtracks to recent ads for Levi's, which used the Death in Vegas track 'Dirge', and Orange, with the Faithless track '8pm'.
Adam Bradley, marketing manager of brand partnerships at BMG, said: "The strength of this site is the virtual studio where creatives can experiment with their project and evaluate the suitability of tracks online. We hope that this will become an indispensable, easy and fun tool, accessible 24/7 via a desktop icon."
