the DVD/streaming releases of Daria suffer from this. i used to have old TV rips of the show with the original contemporary MTV soundtrack but i'm not sure what happened to them. the stock music just doesn't carry the weight of the times.
I was literally complaining to my partner about this exact thing last night -- we ended up torrenting a collection of what look to be old VHS rips and really enjoyed them.
Mission Hill as well. If you want the original one, with tracks by Moby, Looper, the Toasters, and more, the only option is a fan made restoration project
If you want 4k, that fan restoration project is also the only way to get it
