I'm curious why certain shows from the same era of television have issues related to licensing music that was on the show when it originally aired and others don't.
For example the show Felicity which ran in the late 90s has the same music in the background of scenes that played when the show originally aired vs a show like Daria which also ran in the late 90s. The DVD release of Daria didn't happen for a long time because all of the tracks used when the series originally aired had to be replaced due to the amount that would have had to be spent on royalties for the music.
This seems to be an issue for some shows and not others. Is it purely a budget issue or do other things play into a show's original soundtrack needing to be replaced during re-release?
