I personally am a fan of Megatrax. I collect music that was used in WCW (World Championship Wrestling) and they used over 80 tracks from Megatrax, some of the most wanted tracks. I am aware that a channel used them in their adverts for Ghost Whisperer too, this is how we initially knew that the tracks we were looking for were production. We eventually came across Megatrax and am thankful for it.
