One December,
You are in the casino, but about a quarter of the cards are missing.
You see a blue bird fly past the window.
A person walks by you and you think like #TheDress.
I know this is definitely not a good poem, but each line represents a song from that composer. Find who the composer is.
Hint 1: All 4 are pop songs. The last line represents a song that she (yes, it's a she) sang but is not very famous.
Edit 2: For the previous edit, I accidentally put "changed a word", it's more like "added Hint 1".
Hint 3: All sentences are hidden by word play. This isn't a cryptogram. The phrase which hides the songs are in bold in the spoiler:
First line:
One December,
Second line:
You are in the casino, but about a quarter of the cards are missing.
Third line:
You see a blue bird fly past the window.
Fourth line:
A person walks by you and you think like #TheDress.
