All Pokemon games has there own tunes in every place and every game.

What music is really the most one you like is it from the red,blue,green,yellow,fire red,leaf green,gold,silver etc. and why did you like it?

My favorites are from the red version in the Pokemon Center,while riding a bike and using surf because it reminds my childhood memories.In Ruby,is in the Petalburg City or in Mr.Briney's House because of it's high tune something it's just high.Also riding a bike and in Route 105 because I just like it.

My favorite pieces of music are the battle themes from RBY: Battle with a wild pokemon, battle with trainer, and battle with gym leader. Those are the only in-game songs I actually listen to. I really like the intricate melodies, which I never really appreciated when I was younger. I think it would sound nice if a group of people did an instrumental cover on them.

I like the music in the starting screen of yellow, red and blue. The BGM in Evergrande City sounds cool too.

I like DP music by far the best. RBYGSC music was too electronic-sounding for me, and the guy who made the RSE tunes needs to be beaten with the horn he abusively tooted on all throughout the game. But DP had a nice, harmonic feeling that I feel goes well with the serenity of Sinnoh. I especially like the music in gym battles, the pixie's caves, and on the Snow Routes.

In RBY, my favourite music is the tune played during wild pokemon/trainer battles, just like SS said. If you listen to evrything that's going on, it's really cool.
In GSC, I like the music played at Mt. Moon. The outside place. Where you find the Claifarys on Mondays. It just stands out in my mind.
In Emerald, my favourite is the music played in the museum in Slateport, by far.
In D/P it's all good..

Here's more for me:
Battling a Pokemon in RSE because it's awesome. Rescue team base in PMD because it's peaceful,the friend area of Bulbasaur because it's also peaceful and sounds cute.My favorite is in entering buried relic (1-25) it has a high tone.

I generally dislike all pokemon music, unless it's taken and remixed for a game like SSBB. I love SSB/M/B's remixes for pokemon music, they are actually worth listening to.

In no particular order (I swear I did this somewhere else):

RBY: Gym Leader/Lance battle
RBY: Champion Rival battle
FRLG: Champion Rival battle (remix)
GSC: Gym Leader battle (remix)
RSE: Champion battle
DP: Galactic Boss Cyrus battle

^The small text is due to minor spoilers.

All of these musics get my blood pumping. I have purposely never advanced any more on my Crystal version just to hear the fourth music. Now if only I could hear it with headphones in a DS rather than a GBC.

I like:
Cerulean City-LG/FR
Lavender Town-same game
Goldenrod City-Gold/Silver
Snowpoint City-DP

I got a nice amount.

DP:
Game Corner
Cynthia Battle
BEFORE Cynthia battle (I love the piano)
Bike music (who knows why...)
It's not exactly music, but I like Arceus' and Regigigas' cry -> ->
Galactic HQ (Again, who knows...)
Pokèmon Center daytime (only if I'm bored.)
After beating Cynthia/Prof. Rowan's lab (it sounds like a victory/revolutionary song)
After you get your Pokèmon in the record machine AFTER Cynthia (mouthfull.)
AFTER THE ABOVE (the music that starts with the guitar)
Intro music (before you actually start the game)
Mystery Zone's music ;B
Battle Tower
Sunyshore City
Canalave City
The three lakes Electric Piano :F
Stark Mountain
And some others that I forget sometimes.

RSE:
(Emerald) Frontier Brain's battle music (I can still remember beating Nolan...)
Intro Music (Where the legendary appears)
Sootopolis City
Slateport City
Trick House


And that's all folks.

the elite four in battle and out of battle for RSE

and the cyrus battle on spear pillar

oh and spear pillar out of battle

Surfing in blue version

i loved my blastoise in blue and everytime i surf in blue it just brings back old memories of him

the Cyrus battle in spear pillar and the Psychic Trio music are by far the best in the entire series.
