Can't download songs

[TheoKC]

Hey guys,

I have a Premium account but the problem is I can't find how to download all of my songs on Windows. There is no "Download" button in the "Songs" tab from "My Music". The only solution I can find is to add every song to a playlist and download it but I it's very very long to add one by one, maybe we can add all the songs in one time ?. 

Anyone have an idea on how to solve this please ?

Thanks !
