In either case, where are the > "ghosts" coming from? This is an unmistakable sign that the recording was tape mastered. What you are hearing is caused by the tape being magnetized by the data that is on adjacent layers as the tape is wound on the spool. A good recording engineer will use thicker tape and will not let the recording level exceed the threshold of this bleed-through effect. However, there are a number of recordings with this problem on the market.
