Some Tracklib.com sample songs not playing... anyone know y?

So occasionally, I'll download a song from Tracklib.com that I want to sample from and it plays fine on my computer, but the MPC won't preview it. Not only will it not preview it, it won't load to a pad properly. Any ideas as to what the issue could be? As I said, my Foobar 2000 plays the file just fine on my Windows PC, but the MPC live 2 can't read it for whatever reason. TIA for any helpful replies. Peace!

Speaking of; It would have been a lot better for our MPCs to have a direct connection to Tracklib than Splice, I'm just saying...

Some audio has non standard data embedded within it which mpc should ignore but sometimes it struggles. Bandcamp is known for this, perhaps tracklib uses similar techniques. Try resaving the audio in audacity or a daw, it should strip out the non standard data.
