My favorite massage music with lyrics is Stephen Micus. The Garden of Mirrors is my fave, followed by To the Evening Child. I also like Life a lot, but it's not for your average client--there's alot of gong and--how do I describe it?--asian chanting in it. But so beautiful and it really creates a pictur in your mind's eye if you let it.
And I swear, if I ever hear Enya's sail away again, that's what will happen to the CD player! It will sail away through the window!
