It's a bummer that the show will never play with original music on some streaming service due to (as I understand it) music licensing problems.
The solution there is to not bother with "streaming services" and just download the readily available alternative captures, which include the original music.
There's a DVD box set that has almost all of the original music!
Northern Exposure had similar problems but, as I understand it, at least some was resolved for the (somewhat relatively) recent DVD box set release.
It just wasn't an issue that was seriously considered by a lot of studios(?) at the time and it's not like back catalog TV shows are usually these big money-makers that warrant a lot of time and cost to get in order.
