Background city sounds on CD"s?

[DONFLA]

Does any one have long playing  background sounds on CD"s?  Can you tell me a good source for them ?

 Would like to hide some small speakers 1 1/2 or 2 inch in side some background buildings and use a small CD player.  Any suggestions ,  Ideas?

 Thanks,  DON

I don't know if these are stand alone CD's or if you have to use their hardware.
