When I try

To pay for the product that you had up on

Your website just the other day

It’s not cool

Say it ain’t slow

Your site is unbearable

Say it ain’t slow

My business is going elsewhere

Dear website

I try you, in spite of years of slowness

You’ve cleaned up, got faster, (even) using a CDN now

This gigan-tic image, awakens ancient feelings

Frustration, desperation, all of your customers are goooooonneee…

Yeah, yeah, yeah, yeah, yeah

Say it ain’t slow

Your site is unbearable

Say it ain’t slow

My business is going elsewhere
