I have read about 20 posts about this and I'm sure there are many more.  All of them basically say to do a clean install and try again.  None of the solutions posted seem to work for me.  

I am using a brand new Moto G LTE on Adroid 4.4.4 that has about 5GB free on internal and about 30GB free on a new SD card.  The SD card works fine in other devices.  

I have tried doing a clean install.  Followed every step to the letter.  I have used file manager and there is no trace of spotify before I re-install the app from the play store again.  No matter what I do spotify puts the music on my internal storage.  

I'm new to spotify and on a 30 day Premium Trial and honestly if I can't get this to work I'll probably just stick with the free service.
