I had a coworker who cited music licensing as the sole reason he can’t find his favorite show anymore: The Drew Carrey Show. Whatever schmuck owns the music licensing refuses to cooperate with the rest of the show owners, so it can’t be streamed or distributed anywhere.

Another example would be Scrubs, most of the songs used in the show (including key moments and the OG songs were perfect for them) have been edited out and replaced because of licensing issues. Unless you’ve got the DVDs or pirated older versions, you’re stuck with the new music and it’s not the same.
