Mhmm... can't say I agree.
It might be nostalgia knocking on the door, but I think the original Sonic the Hedgehog intro for the Genesis is the best.
Not to knock these tunes though.
It's just that the early 90s MIDI synthetic, pop music that accompanied the original Sonic games is impossible to replace. It's part of the essence of the Sonic the Hedgehog.
It would be like trying to put edgy, Linkin Park-esque music in Mario games. It would just be out of place.
The Sonic franchise as a whole fell apart with its attempt at going 3D, music included.
Just my opinion.
I think I would've rather they took the music from the Genesis games and recreated them much akin to what Nintendo did when they took all the classic game songs and had a full orchestra play them for Smash Bros. Brawl.
It just sounds too animé-ish. Save it for a new Sonic cartoon series or something.
