The problem is that for the elite skaters, you see those programs at least 3 times, and as many as 5 times in one season (2 GPs and Worlds, and maybe 4CC/Euros and the GPF as well---and not even counting Nationals). That means in the second season, you are seeing that FS for as much as a 10th time. When the skater has chosen an especially dog-eared piece of music, that can be downright annoying.
I know I got awfully tired of Lysacek's Carmen after half a season, and his "Tosca" program is just as grating. I'm afraid we're going to see it again next season because he didn't do it at 2008 Worlds. I sure hope not.
Repeated SPs aren't nearly as bad, because ESPN didn't usually show all the GP SPs anyway. And they are blessedly brief.
I look forward to seeing new programs (at least the FSs) from skaters each season. I'm always disappointed when the FS is a holdover from the previous season.
As for Junior skaters, they don't get the exposure that the Seniors do, so we're not seeing their programs multiple times each season. So it isn't quite as bad if they repeat, but the top Juniors rarely do that, because they are exploring different types of music and working on their expression. In a sense, for them to repeat is to stagnate some in their musical development.
