API played_at not matching

[jechave]

I have noticed something strange when fetching data from the API.

I have played two songs in a row(without pause or anything), yet the result of the API (played_at and track duration, doesn't add up when compared to the next played_at timestamp). 

Basically data does not show that the playing has been continuous even if it has been.

Any insights on this? Is the played_at timestamp the start of the playing? 

Thanks
