I think you might be a
Street light
Sleeps through the day, awake in the night,
Street lights are usually set to come on when dark
To brighten and shine, is their delight.
They light up the darkness.
A few may seem, like their missing their sheen,
Street lights are normally not cleaned very often and can lose their sheen quickly.
Right in the city, it's where they have been.
Mostly are located in cities.
Go through the day, mostly unnoticed,
Street lights are not switched on during the day.
Right in your face, I'll give you focus.
Not sure about this one, but possibly, if you are about to bump into one, you will be more focused.
Over the streets, you will see my feats,
The lights themselves are above the streets
Under the sky, you will see me lie.
Street lights essentially act as artificial daylight.
Not fat and round, I'm bound on the ground,
Street lights are connected to the ground, usually not fat and round.
Dawn upon us, I wait for the bus.
Street lights are often positioned near bus stops.
Hidden clue
The first letter of each line spells STARGROUND which could be a hint for a street light.
Title: Don't Stop Believing
Part of the lyrics of the song are
Strangers waiting
Up and down the boulevard
Their shadows searching in the night
Streetlights, people
Living just to find emotion
Hiding somewhere in the night
