Ironically, the music is not bad
I think I've said all that really needs to be said about Capcom's free-to-play abomination that is Rockman Xover. But in all fairness, I have not personally played the game and thus can't judge the accuracy of others' damning impressions... yet. Capcom is still tooling around with the idea of a localized release, so maybe I'll get that opportunity one day.
While those chuckle monkeys get that business sorted, you can download Xover's soundtrack from the Capcom sound team page complete free of charge. Composed by Masahiro Aoki, member of the in-house Capcom band ROCK-MEN, the music departs from the series' usual electronica styles and enters full hard rock territory with wailing guitars that wouldn't feel out of place in Guilty Gear. It's surprisingly not complete doo-doo, and the main theme is quite catchy.
On the downside, it's only six tracks long. One track was added to the game along with the fan-created Arcade Man boss, and another is a piano / violin arrangement of the main theme. In other words, the game only had four songs initially. That's kind of pathetic, but whatevs. To download the individual tracks, visit here and click on the song titles under the "REVIEW" section.
