I'm a bigger fan of DP music actually.=/
Guess I'm a bit different.
GS music really didn't do it for me but it was okay. I didn't mind Johto music. The only music I really liked in Johto was the music in the building with those Eevee evolutions trainers and the Suicune music in Crystal. I use to like the final Pokemon league champions music aswell except when playing it through now the music doesn't seem as great anymore for some reason there. It's okay still and that's all I can say. Though I like the crazy remixes people put online so I'd probably like a remix tune better if it ever happened. I think there was a remix tune in FR and LG on one of the islands from GS. I liked that better than the original.
I hated most of the kanto's remix music in GS though. I'd take red, blue, yellow's old music over that remix. The only kanto music in GS I liked was actually the Gym leader battle and that's it. LG and FR did a better job at remixing it. It gave me a different feeling that I just didn't like.
Guess I'm in a different sector when it comes to to music.
My favourite music is mostly in DP, RBY and LG and FR.
Then it's goes Emerald, RS and then GS. Though GS rises when I hear remix music of it. I usually turn the sound down to nill when in kanto in GS and only turn it up when there's a gym leader battle since that's the only tune I liked in Kanto in GS. The other tunes rubbed me in a bad way. I can't explain it in all honesty.
Johto's okay. Not much stood out for me but it was okay.
