"It Ain't So"是由Weezer演唱的一首歌曲，歌詞如下：
It ain't so, yeah
It ain't so, yeah
Verse 1:
I'm feeling down, I'm feeling blue
I'm feeling like my world is through
I thought I found the one for me
But now I'm thinking it just might be
Chorus:
It ain't so, yeah
It ain't so, no
I thought I had it all figured out
But now I'm thinking it just might be over
Verse 2:
She said she loved me, she said she cared
But now I'm thinking she was just a matter of time
I thought I had it all figured out
But now I'm thinking it just might be over
Chorus:
It ain't so, yeah
It ain't so, no
She said she wanted me to be her man
But now I'm thinking she was just playing games with me
Bridge:
Oh I thought she loved me, oh she did
Now I don't know what to do
I thought I had it all figured out
But now I'm thinking it just might be over
Chorus:
It ain't so, yeah
It ain't so, no
Oh it ain't so, yeah
Oh it ain't so, no
Oh oh oh oh oh oh oh oh oh oh oh
Oh oh oh oh oh oh oh oh oh oh no
