When some of you say "From ?? onward..." you realize you are also adding in the final chorus/ad-libs and going beyond the bridge, right?
Anyway I can't single out just one, or even just a few. I need to go through each album.
"Vision of Love" - The classic bridge on this is strong enough as it is (love the "Feel so alive"), but then the duetting Mariahs kick in. I assume that counts as a bridge, too? Epic.
"Love Takes Time" - This is one of her more emotional bridges to me; that "But I know that you do and I feel that you do" is so gritty and soulful
"Can't Let Go" - This is like the bridge in "Love Takes Time" for me in how emotionally immediate it is.
"If It's Over" - I'm surprised this one hasn't been mentioned; another really solid bridge emotionally, vocally, and taking a song to another level.
"Til The End of Time" - The bridge on this is really nice, but I think some of you are also factoring in the final, epic chorus.
"Just To Hold You Once Again" - The bridge on this is just a classic bridge; it takes the song up, and it's nicely emotional.
"All I've Ever Wanted" - This is one of my least favorite songs from MC, but there is no denying the epic vocal on the bridge.
"All I Want For Christmas Is You" - I love the sped-up "Santa won't you bring me..." This song is hook after hook, and the bridge is another great one.
"Fantasy" - Mariah singing part of "Genius of Love" as the bridge was, well, genius to me. I love her vocal on that.
"Underneath The Stars" - While not as epic vocally as some of the others, I love the vocal arrangement on the main melody and then how Mariah's ad-libs weave through like the breeze
"Melt Away" - The bridge on this one is key for tying the song to the heady/daydream feel of the album.
"Forever" - This is another example of the classic use of a bridge taking a song to a higher level as it leads into the final chorus. Mariah hasn't done this in years.
"Looking In" - I have to throw this one in just because I love how Mariah sings "Please understand" and how it sets up the final verse emotionally.
"Butterfly" - This is obviously one of the best bridges in her catalog. The lyric and vocal are really emotional, and they lead into an epic final chorus.
"Close My Eyes" - This is one of Mariah's best bridges lyrically, and I love the heady feeling of it; it rings true with the lyric where Mariah wakes up just in time.
"Petals" - The bridge on this song probably punches me in the gut more than any other; I want to cry thinking how abandoned Mariah must have felt.
"You Had Your Chance" - It isn't grandiose or anything, but I've always found the bridge on this pretty catchy. It's also pretty emotional when you consider it's about Luis not being there for her during the breakdown.
"We Belong Together" - It's different because it follows a verse and not a chorus, but I think "I'm feeling all out of my element..." acts as a bridge into the final chorus. That whole verse/bridge is my favorite part of the song.
"Joy Ride" - I love the strings throughout this, and the key change is of course great.
"So Lonely" - So sexy.
"Side Effects" - I think the bridge is the catchiest part of the whole song.
"I'm That Chick" - I agree the bridge pumps some energy into this track; best part of the song.
*While E=MC2 doesn't have any real classic bridges in the 'epic' sense, there are several that are nice in a different way.
"HATEU" - The bridge changes the emotion of the track, and that works in the context of her moving on.
"Candy Bling" - The bridge on this speaks more to me than all of "Bye Bye."
