A lot of TV shows had their music replaced when they went to streaming because of song licensing crap, so it wasn't super surprising that it happened to a movie too.
NBC and owners of scrubs were the worst for it. Scrubs had an iconic soundtrack that picked songs for the exact mood of the story, but then licenses expired and they just chose cheaper songs. I don't care how much it costs, when "I will try to fix you" comes on I immediately start tearing up.
This is why I have it pirated, as you say the soundtrack is a huge part of that show, just rewatched it again recently and I don't even want to know what the streaming version is like.
Music licensing is a nightmare. Music licensing across international borders is a ridiculous surrealist nightmare from which you can never wake; if you should ever want to enter into such endeavors find the nearest cliff and try to fly as that will be a less painful adventure more likely to find success.
