Is it a private library?

Her favorite song echoing across the walls
She traced the lyric
and followed its rhythm
A small-aged-wooden door led her wonder

She was on her tiptoes
Peeking through the peephole
She gazed and gazed
Thin rim glasses surprised her

Without any card scanned
They entered the room
Unmeasurable miserable doubts
She was going along

Some sturdy bookshelves

Some crinkled pages
Some bindings lost their glue
Lots of books existed

She scrutinized the room
and devoured each title
The smell of old books finally soothed her

After all she guessed,
Is it a private library?.
