When one of the main characters in the series is an idol singer, you need a composer who can craft both score and songs. Kanno did both on Macross Plus. The other issue was that the idol was popular because she could sing any kind of song and appeal to any kind of listener. So the variety of songs is pretty interesting and impressive. Now keep in mind this was made in 1994, so much of the pop sound in these tracks is very grounded in the 90s.
The song I'm featuring is Pulse, which should remind listeners of the group Enigma who shot to fame in the early 90s with Sadeness Part 1. The opening music is actually used in the opening title card for Macross Plus, and the rest of the song appeared in various forms throughout the series. So here is Sharon Apple singing Pulse with a little help from Akino Arai.
