Hey now the load times are well worth the wait in Cosmic Fantasy 2.
The load times for the cinemas, sure, but waiting for the track to seek for every fight, back to map, back to fight, back to map sequence is bullshit, especially since you just end up hearing the first 3 seconds of each song over and over again and never the rest of it.
For an example of how to do a MUCH better job and music transitions into and back out of random battles, see Tengai Makyo II. Zero waiting for music access. Decent chip tunes for the fight. AMAZING map music. End result: better music, better fights. The fights that take 1/16 the time and you get to hear the entire piece of music.
