[slimnhottt]

i love this song but i like the version without claude kelly better

[Detsurasu]

It's so sad, they are not like before and this turns into RnB. :( Give us back the '90s!

[janee7791]

Too bad you don't like it. But I love the new album.

[sh0rtymac85]

They have done R n B before, listen to "not no more", "If you Stay", "Dont want you back", " Hey mr. Dj". "Get another boyfriend", "song for the unloved Rnb Version". I think they sound good doin it

[TheAnu90]

aj sung 1st line...

[glennbizzle]

i correct myself...Claude is the first line, you're right sorry lol.

He's not in the final version of the song though.

[Wijkbijduurstede123]

nooo, claude kelly's version is way better!

[JoshuaGilmore101]

just listenin to this song they have really stepped up their game! This is what people wanna hear these days! Not slow boring songs.. ya know? yeah.. right on for bsb. =]

[chaldobabi4life]

even though aj isnt my fav bsb but woww he sound good ;D

[irichmusic]

Claude Kelly sounds alot like AJ. He gets the first line, and then AJ gets the following lines after CK.

[glennbizzle]

CK isn't in this song...he just wrote it

[inahboi]

love it

[mrspicasso]

Let me clarify- I don't know if someone else is singing with them on THIS uploaded version, but on the final, it is only them.

This is not a HQ version, so it is hard to tell.

[mrspicasso]

No one is singing with them.

"If I knew then" line is sung by AJ

[xXcuteDanXx]

who the fuck singing with bsb ?

he was like what i knew know he's voice was like a SHIT

Seriously !

[gaasasu33]

Love this song!!! Backstreet Boys are the best!!!!! =]

[emmibsb]

love this band

bsb r the best

[halawa1312]

Wo0o0o0o0oW

[BACKSTREETGIRL4BSB]

I love the BSB only version better. This version just doesn't reach me as much as the other.

[chaldobabi4life]

omgg aj in this song sounds sooo hott :D

[WERTGRE]

I think the boys singing this song alone is better, especially AJ's part.

[feha185]

@WERTGRE ur damn right

[jaypay09]

just keeps gettin betta. they should release hologram ft. andre merrit and chris b. i like that version more

[popamonkey190]

I love both versions equally. BUT I ESPECIALLY LOVE CLAUDE KELLY!! <3

[vh1212]

originallll better?

[leelawrencee]

amazing song

[flowjam21]

Wow! amazing song again,Is this included on This Is Us Album?Coz,I love it,the upbeat is pretty much awsome.Can wait the album.

[Ximenex]

I like better when aj sings alone!!!!!!! i dont like that gay T_T i prefer the bsb alone!!!!!!!! xD

[zdiiriye]

He isnt gay...u dumb bitch! He sings demos for artists (reason why he sings both grls and guys songs)...plus its his song...retard..get your facts straight! tsk tsk tsk AGAIN DUMB BITCH

[Ximenex]

im sorry i ment guy but i wrote gay i didnt mean it like that :S but really u dont have to insult me :D thats just my opinion

[jaypay09]

WORD!

[GERWhisky]

i like claude too hes cool

i love bsb and these song

[RockAnRepublic]

wow shut the fuck up claude kelly is amazing he freaking made this song if not for him it wouldent exist!

personally i think claude kelly does the chorus better but bsb does the verses better.

[tntnijmegen]

Indeed.. Claude Kelly was made for this kinda songs. He makes this song so much better.

[A1DSBSBWLFan]

At first I thought that it was the demo of this song

[ifutman]

their album will be the best

[SuperPwl]

good job bsb , you R the best

waiting for the new album <3

[samumathew]

i like this...song...

their album is also gnna be gr8...and also will get new fans...

comparing their previous 4 - 5 albums...and also their previous album...they hav become more on RnB....

but they still rock...

SAMU

[xxoxxmileyrocksxxoxx]

BSB R amazing

i <3 there new album and OMG who wuld havethought BSB doing R&B but the r really good at it

I <3 BSB

xx

[marisolbsbhere]

great sOng !!*

bsb

they are the best , foreveer!

I ♥ BSB

[TheJd2786]

I've been a fan for 10years and appart from stmh I think this is their best album ever, I love the whole pop/R&B sound they have going on.

[93aree]

They are looking for a newer market now...this sound may give 'em new fans but the old ones would fade...

[bridgetj5]

The song's alright, but from what i've heard so far, I think their new album is going to be my least favourite of all of them.

It's prob not really my cup of tea, but I think that BSB could gain a lot of new fans. I only hope that it's not at the expense of fans who've been loyal to them for more than 10 years now.

[LittrellCarterLover]

yuppers BSB are still together since 1993 and staying strong till forever.

[shakiikora]

they kinda sound like a NKTB knock off.lol

its okaaay.

[LittrellCarterLover]

NKOTB knock off. No way never will be!

[shakiikora]

nobody said anything about them being as good. OF COURSE NEVER . I said knock off. wannabe's . LMFAO

[brianbf8]

More Autotune...thanks BSB for copying what every one else is doing out there.

[FFOUOZZIE1]

Bsb if the management ....RELEASE THIS AS A SECOND OR THIRD SINGLE !!!

Just a smashing hit...Tje voices just fit in perfectly...and the beat is sick !!!...yeah...

[jinzo0086]

ah shit. almost all the songs i heard...im sure everyone these days could listen to. it has the pop/rnb sound these days. which is good for them to use this tactic.

[amandalittrell]

não tem a voz do brian :/

[ligyro]

each new bsb album is getting closer and closer to being something i wouldnt be embarrassed by playing it in my car. hopefully this album will have a couple non-gay songs. going to keep buying their albums regardless and listening to them in private :p

[GakiGirl86]

It's a fake or it's a real thing?

[seeingstarrs]

wow i didnt know they are still singing togeter luv the song but
