Dancing with my phone (Explicit) - HYBS

Lyrics by:Kasidej Hongladaromp/James Alyn Wee

Composed by:Kasidej Hongladaromp/James Alyn Wee

I'm just laying on the floor again

I'm just laying on the floor again

Can't be bothered to get up now

Can't be bothered to get up now

I wouldn't care

If I never get up again

I don't want to

Then our song comes on the radio

Then our song comes on the radio

Makes me wanna start to dance

Makes me wanna start to dance

Oh I wanna know

If you feel the same way as me

Why would you go

Dancing I'm all alone

Dancing I'm all alone

Figuring out how I can get you home

Figuring out how I can get you home

Dancing with my phone

Dancing with my phone

Thinking about you

Thinking about you

On my feet and now I'm out the door

On my feet and now I'm out the door

Walking by the places that we used to go

Walking by the places that we used to go

I remember all your favorite stores

I remember all your favorite stores

I won't lie

I don't think I even know myself anymore

I don't think I even know myself anymore

You're the one who knew me f**kin' well

You're the one who knew me f**kin' well

Yeah you know

Dancing I'm all alone

Dancing I'm all alone

Figuring out how I can get you home

Figuring out how I can get you home

Dancing with my phone

Dancing with my phone

Thinking about you

Thinking about you

Dancing I'm all alone

Dancing I'm all alone

Figuring out how I can get you home

Figuring out how I can get you home

How I can get you home

Dancing with my phone

Thinking about you

Thinking about you

Dancing all alone

Dancing all alone

Dancing all alone dancing all alone

Dancing all alone

Dancing all alone I'm dancing with my phone

Dancing with my phone

Thinking about you

Thinking about you

Dancing all alone

Dancing all alone

Dancing all alone

Dancing all alone

Dancing all alone

Dancing all alone

Thinking about you

Dancing with my phone

Thinking about you

Thinking about you
