SO, long story short, I bought spotify premium, I downloaded a playlist with over 300 song on my phone so i could listen to them on my week long trip in canada. For some reason, the first night, gone, i have to be online or redownload them, problem is, wifi sucks and wont download and using 4g will cause my phone bill to shoot way up. Is there a way i can take the downloaded songs from my computer and sort of transfer them over to my phone or some way that doesnt require me to use my phone?
