Why? So many skaters have used it--Jenny Kirk, Orser, even Plushy.
I think certain pieces are definitely owned, or dominated by certain skaters. Similar to how Bolero brings back comparisons to T/D, other pieces of music can also bring certain comparisons. I think Jenm is right in saying that Danse Macabre is very strongly associated with Yuna. When watching Sergei Voronov's Danse Macabre this season, I could only think of Yuna's and how lacking Sergei's performance was.
