音楽集/Ongakushuu is just written on the front jacket, otherwise it is ミュージックコレクション/Music Collections on the spine/obi/CD (both prints). I added a fourth line in the titles for Ongakushuu, i don't know if it is really useful...
According to several sources, there's a movie for Janperson, released on April 17, 1993:

http://www.imdb.com/title/tt2075358/
So this soundtrack released later in July also concerns the movie, in addition to the series. Is that why it is written "Music Collections" with a "s", o is it just a writing error?
Then I'm not sure about the romanization of the singer 大矢晋, is it Susumu Oya or Susumu Ooya? (I can't write Ōya) I found the 2 romanizations on VGMdb.
