Well great music is Sonic standard after all (unless you're RoL which is... no music at all).
Also I digged this up from the SSMB boards. Apparently one user commented what Nakamura's interview about Sonic at TGS 2017 a while back about Sonic Forces:
"So I listened through Nakamura's interview at the 2017 TGS 1st day a while back, a few things I made sense of from it that are relevant:
"In Japan [people say] 'he's too fast', 'too many characters', or something, so [Sonic]'s not yet popular here... but of course in America and Europe [he is.]"
He wants to bring back the "feeling" of SA1/2 that has faded over the years. (Nakamura said he started working on Sonic games with Adventure 1. Also it was pointed out here that Adventure outsold the classics in Japan.)
Anime is self-consciously being amped for Japanese players, in terms of "serious" story and vocal music. He hopes Americans might "grow to appreciate" it as well.
The avatar would be big in bringing new players to the series.
Bottom line it feels from his side that they are making efforts to try and reach a larger Japanese audience with Forces. They might make be making a bigger marketing push than usual in Japan if they are hoping to improve sales compared to typical Sonic games. Trying to ape Mario in Lost World might have been done for some similar reasons. (Not that it helped there.)"

Plus it seems like people dislike Sonic going "too fast" which is probably why they might've disliked the Classic Sonic games with the momentum-based speed and the recent change to having only Sonic playable as there's too many characters. In a sense this is SEGA of Japan and Sonic Team is Japanese-based so they're trying to get Sonic popular in Japan first and so far they're only trying to cater to their fanbase before the West.
Might be why a lot of people in the West are disappointed. This game is not made with them in mind even if they're the more devoted fans of the series. They're just hoping the American just "go along with the changes" to the Sonic series. This is kinda backwards thinking a bit.
Something tells me the Boost gameplay is going to stay a little longer and the Avatar is going to return one way or another.
EDIT/UPDATE: Forgot to post this new video by Dr. Eggman!

This reminds me of the old 1950's commercials of the past. Damn, I kinda wish this was in the base game now.
And... Sonic Forces got into the "Platinum Hall of Fame"?
