Chorus:
hey oh la da dee doe la dee doe
sometimes i feel like its madness
sometimes i dont know what to do
hey oh la da dee doe la dee doe
and when i'm looking for something
and i cant seem to find it
what should i do

cuz boy
i'm looking for something
and i know what i want
but it isnt you

Chorus:
hey oh la da dee doe la dee doe
sometimes i feel like its madness
sometimes i dont know what to do
hey oh la da dee doe la dee doe
and when i'm looking for something
and i cant seem to find it
what should i do

yeah the emptyness is killing me
i'm wondering when i'll find another

as i look back at the photographs
and i fight back tears and try to relax
cuz you came and you left and it all went by so fast

Chorus:
hey oh la da dee doe la dee doe
sometimes i feel like its madness
sometimes i dont know what to do
hey oh la da dee doe la dee doe
and when i'm looking for something
and i cant seem to find it
what should i do
hey oh la da dee doe la dee doe

This is a perfect pop song,

I can hear it now 'hey oh la da dee doe la dee doe'

Just get up and do it, it looks like you could!

What about molding this short bit :

"cuz boy
i'm looking for something
and i know what i want
but it isnt you"

to fit into the rest of the song, to come in more often, I like it, it's catch and coming from someone like you in a few years time, it would be really cool 'attitude' for a 'pop' song

repeat the 'but it isn't you' bit a few times at the end.
