Fascinating reply - I guess buying the audiophile version is the way to go but it is incredibly expensive. And, I cannot imagine how big a 7200rpm hard drive I would need to store them.

I guess you are saying is that for each song I have selected and settled on a set of RT's for I could uncompress those only. So, for each song I would be doing different uncompresses. I do not have a program to uncompress but I use iTunes (it has a file converter) to do that and it works really well.

I never considered actually cutting a piece off of a PG RealTrack. This is a totally new thought for me. I have found some of the acoustic guitar strum RT's to be lagging. I might give that a go.
