2001年同获滚石杂志与AMG四星高评的专辑《Room For Squares》，不仅销售至今连破三百万大关，发片１年多仍在全美百大专辑榜中徘徊不下，2002年还在潜力榜中回升至冠军宝座，流行榜也有第八名的佳绩！专辑中的强打曲《No Such Thing》、《Your Body Is A Wonderland》纷纷蝉联成人抒情榜数周冠军，《Why Georgia》也晋升至亚军的位置！
受到乐界前辈的赞赏与提拔，并获音乐各奖及提名的光环加身，并未让John被这突如其来的名利冲昏了头，继续依循着惯有的音乐态度与执着，虔心审视这几年的转变，再次幻化为动人音符于相隔两年所推出的全新大作《Heavier Things》中！依旧请来合作愉快的Jack Joseph Puig(Sheryl Crow、No Doubt、Beck)，负责制作与混音的工程！宣露出流畅吉他摇滚声线，John真假音交替等情绪转换下，首支单曲《Bigger Than My Body》呈现如No Such Thing般讨喜耐听旋律；渗入淡淡乡村／蓝调摇滚曲式的《Come Back To Bed》，听毕后有种莫名的感动慢慢蔓延着……清新民谣风的《Daughters》给您毫无压力的聆听感受；回绕在淡淡爵士律动下谱以轻柔摇滚攻势，都再次让您无法抵挡John Mayer极具个性化的魅力与毫无刻意矫揉之作！
Daughters
~ John Mayer
I know a girl
She puts the color inside of my world
But she's just like a maze
Where all of the walls all continually change
And I've done all I can
To stand on her steps with my heart in my hands
Now I'm starting to see
Maybe it's got nothing to do with me
[CHORUS:]
Fathers, be good to your daughters
Daughters will love like you do
Girls become lovers who turn into mothers
So mothers, be good to your daughters too
Oh, you see that skin
It's the same she's been standing in
Since the day she saw him walking away
Now she's left
Cleaning up the mess he made
[CHORUS]
Boys, you can break
You'll find out how much they can take
Boys will be strong
And boys soldier on
But boys would be gone without the warmth from
A woman's good good heart
On behalf of every man
Looking out for every girl
You are the God and the weight of her world
