[downloaddavid]

hi,

i have an iphone and whant music in my spotify playlist that is not availible on spotify. (acid rap - chance the rapper). i have dowloaded this and followd the steps online to put it in your playlist. i maked sure i use the same wifi network on my phone and laptop, i have the latest version and so on. BUT when i have the songs on my phone in my spotify playlist the titles of the dowloaded songs are darker then normal and i get the message: "you can sync your downloaded songs from your computer" but how?
