Spotify Wrapped 2018 ?

I just noticed interesting thing after purchasing djay pro 2 in december 2017.

The spotify wrapped is calculating the time you have used to listen music (1.1-31.10 each year)

In 2017 I listened 12161 minutes, which was as excepted.

But in 2018 I listened 195846 minutes.
That would be 195845/304 = 644 minutes roughly 10h each day between 1.1-31.10 :o

How about you?

I might have an idea how this is related to djay pro 2, but have you?
Or actually there might be a bug how they calculate the data…
