variations music

[123enpointe321]

I have been trying to find music for Aurora's third act variation from sleeping beauty. It was on itunes, but it is a weird version that can't really be danced to- it has no intro and there is an extra section of music near the end. Does anyone know a good source of ballet music?? I usually end up burning a copy of a CD someone else has, but sometimes I can't find the music I need. Any suggestions would be greatly appreciated:)
