They said they will try their hardest to find a replacement track, but do not hold your breath, especially as I (you?) did not pay to download it.
Like I said, it did not bother me because I did not use that track.
My only other suggestion, which I have done before if you really want that song, is to just download that one track from another music site?
Although looking at other sites including Fiesta & Millisong, I am not sure that track should be on there???
