I recently deleted my facebook. I have had a premium account with Spotify way before I linked it with facebook. Now I cannot send my friends anything from the app or on the desktop. This is the best part of Spotify, the social aspect. Please fix this! I tried the spotify:user:<username> , This works to find friends and follow or unfollow them, however, inserting this into the "enter friends" column when I select "share" returns a "sorry no results can be found." I can't send anything, unless I send the link to my email and email my friends now. The results cannot be found is clearly not the case when I can search and find them that way, but cannot send them anything.
Please allow us the CHOICE to find friends/use Spotify's social setting and not force us into having a Facebook account. When I first started using Sportify, all I had to do was search someone's name and I could send them things. No Facebook.
