I think a smart competitor will go with music that works for him/her. If it's old warhorses so be it. The warhorse music is used over and over again because it DOES work. It's about points!
What does using the same old music have to do with getting points? You get points for how you skate, not what you skate to. The warhorse music is not used over and over because it works, it's used over and over because people lack imagination and go with what they know, which is not necessarily what they could skate best to.
Yagudin's Winter wasn't an old warhorse, and neither were Gladiator and The Man in the Iron Mask. Plushy had his Carmens and Toscas but he also did Tribute to Nijinski and St. Petersburg 300 (and that Michael Jackson medley, but that's best forgotten

). Michelle Kwan managed to achieve great results while making many original music choices - Salome, Lyra Angelica, Dumky Trio and East of Eden, to name a few. If you're good, you'll get the marks without giving us Carmen/Swan Lake/Tosca/Nessun Dorma/Rach 2, version 300.0.
You can say that it's a great way to get audiences involved, but I didn't get the sense that audiences and judges found it difficult to appreciate Brian Joubert's Metalica LP, or Aliona and Robin's Lost in Space, or Del/Schoe's Pink Floyd FD, even though the music hasn't been used to death in skating.
There are two separate threads on this board, one with classical music ideas and one for film scores. There are excellent suggestions on both. I know FSUniverse also has a thread on this (it is a popular off-season topic

). Normally I'd say it's best for skaters to stay away from fan forums, but in this case, I wish they'd drop by and get some interesting ideas

.
I would say that the best place to experiment is ice dance. But singles and pairs skaters should still take creative risks and try new things, not just recycle music and ideas we've heard and seen a million times. At this point, what possible new interpretation can anyone offer to these pieces? Unless a skater is extraordinarily talented or the choreographer really original, I don't think it's possible to create something new and interesting.
