No, I am not talking about muzak.
After a tiring day, you want to relax to music. Let me offer you arguably the best music there is for this: Cantatas. I just picked
this up and started to listen. Fell asleep right away. Just kidding.

It's better than those mood music with sounds of nature. You can look for those periodic single item coupon and get this for much less. The thing is I have all these on records but CDs still are so much less trouble to play then records, especially when you are tired.
