Not only are there gaps between each tracks, there are no track listings on the download version. The amount of time it takes to correct the download version is ridiculous. Caveat emptor.

There are no track names, the tracks themselves begin randomly, usually several bars before the end of the previous number, and the pitch is nearly a half-step too low - comparing this performance with René Jacobs on original instruments, the Furtwängler performance is playing at something around A=415!! Therefore the tempi are slowed down even further. Avoid this issue.

There is a momentary silence every time a new track begins. This is a sign of amateurish CD mastering, probably track-at-once, where the default gap between tracks has not been disabled. I am a professional audio engineer and I always use disc-at-once mastering. I am in the process of researching an article on the various editions of this performance for a conference presentation and article. None of the CD releases on other labels that you might have copied this from have this problem.
