I think these photos + their captions are all POSSIBLE hints of the fifth album.
Obvious Facts:
1. She loves taking pictures with a SEA in it.
2. The latest photo (the very first picture) has 4 words that ALL STARTS with S
3. There are two quotes that are obviously sad. (I think there will be songs which portrays both quotes.)
4. There has been TWO artwork Tay painted. And obviously, they were both FLOWERS which is probably representing the albums (the 5-flower painting).
BLUE for Taylor Swift (not yet blooming)
YELLOW for Fearless (going down, the small flower)
PURPLE for Speak Now (going left, the slightly bigger flower than Fearless flower)
RED for Red (going up, the res one which is bigger than the two)
PINK for the 5th album (the centre flower which is the biggest)
5. IDK if the Father’s Day photo is a hint but I think there’s a slight slight slight chance of it. But not impossible tho. Just a gut feeling of a Swiftie. Haha.
ANYWAY,
so those are my speculations about the fifth album.
WAIT. THERE’S MORE!
Since the latest photo (First Photo) has a lots of "S" going on in the caption, I am pretty much sure that the fifth album starts with S.
Where are these from..... I know last summer people were saying they were lyrics they found on some sort of personal website/blog/whatever Taylor had but I'm sure Taylor would be more careful with her lyrics. We're not in 2005-2007.
I think those are fan made.
Losing him was blue like I'd never known
Missing him was dark gray all alone
forgetting him is like trying to know somebody you never met
but loving him was red
Remembering him comes in flashbacks and echoes
Tell myself it's time now, gotta let go
But moving on from him is impossible
When I still see it all in my head
In burning red
Burning, it was red
Quite ironic that it's example is "Joe Gave Taylor a camel bite".
