Where are you putting the files on your phone? Have you reboot since putting them on there?
Music players from the market, such as Poweramp can play more slightly obscure formats that the stock player may not. OGG, FLAC, APE...etc Still probably won't play DRM content.
As noted above, if your files are DRM protected, you'll have to use the player from where you got the music. If they are anything but MP3, as was suggested, I recommend PowerAmp.....yes, I am biased!
