Same thing happened bringing Daria to DVD. The soundtrack was a big part of the show and MTV had access to whatever music they wanted so regardless of how long it took to write/animate an episode when the show aired you might hear a song that had just been released. Trying to secure the rights to all those songs decades later was impossible so they replaced nearly all of it with generic music. It's just not the same. The creators know it, and the DVD actually shipped with an explanation and apology.
