Let's try a few things.
Under the Audio options, turn off "Play files from memory" if it's on.
Also in there under "Track Change" use these settings:
Switch Tracks: Gapless
Uncheck "Do not play silence"
Check "Use gapless for sequential album tracks"
Make sure "Use alternate mode settings" is unchecked.
Prebuffering set to 6 seconds (the default).
Finally, if this doesn't solve the isssue, can you put your ear to the Id and listen to the Id hard drive and see if it has to spin up before it plays the next album?
