I really want to know how they picked the journey composer over shoji meguro, that man has literally mastered so many different genres, come on now
While Meguro is also one of my favourite composers (granted, I don't even know all of the composers on this list, I only got really into listening to video game soundtracks because of Persona 5 actually), it's hard for me to be upset about that list.
Austin Wintory for sure has done a lot of video game music and it's usually very good. I would personally put Meguro higher as well, but I can't really argue against the others on the list.
Even though I didn't know some of them by name, you can't argue with a lot of the games they created music for. Eg, I didn't know the name of the Mario and Zelda composer, but it's hard to be angry that he is high on the list.
I am actually happy with that list. I have some names to search for as I got some from the comments on here and youtube as well (I dared having a look). It's just impossible to put everybody with great soundtracks on a list like this. There are so many great composers and it's even harder to put them in order.
Uematsu is weird for me as well. I would probably put him on the same spot, but I was looking for soundtracks to buy of a couple of FF games or Lost Odyssey and while I really loved those games and I really enjoyed the music in game, listening to the soundtracks is usually meh for me for some reason. I get bored with the relatively quickly and there are usually only a couple of tracks that stand out to me.
It's possible I will still buy Lost Odyssey at some point, but only because I love that game, not because I love listening to that soundtrack.
It sounds old to me for some reason, which is weird because I love the Shin Megami Tensei III soundtrack and that one sounds old as well (and I haven't even played SMT III). That said, he is still a legendary composer and deserves the spot he's in 100% imo.
Edit:
I also love both Gravity Daze (Gravity Rush) soundtracks by Kohei Tanaka, but I totally understand why he's not on the list. Not sure if I would place him in the top 10 either.
All in all I am happy with the list. It's a difficult job to make a top 10 list in general and for sure for something like music as there are different tastes and styles of music which makes it very difficult to compare.
