Well, putting hte music in the player doesn't cost money, but Adobe flash, (The program), does. I mean, they literally make the player themselves and put the music in the flash file. DeviantArt can read the flash movie they've made, and will display the player. Sadly, this takes some sort of flash knowledge. You might want to talk to someone that uses flash, other than me, because I personally only have slight knowledge. Sadly, deviantArt doesn't support audio media, mainly due to the fear of audio files being uploaded from famous artists and celebrities.
