Spotify doesn't play the entire playlist

[PatchworkKitten]

I have a playlist which has about 50 hours of music in it (give or take), however when i play it spotify seems to be grabbing a chunk of this (maybe 100 songs) and looping them, this is without repeat turned on.

It also seems to do the same thing when i have it on shuffle, why is this and can i turn it off?

Do i just need to split my playlist up?

This happens on my phone, computer and laptop as well as both on and offline.
