I have Spotify Premium. I had to change devices and took my sd card to the new device. How do I get Spotify to recognize those songs. I don't want to download them again and have them take double the space in the card.
Do you mean songs you added to Spotify, or playlists your downloaded? If it's the later, you may just need to connect to wifi to redownload the playlist. If it's the former, reach out to Spotify Cares on FB or Twitter, they're pretty quick with responses on these types of things.
The playlists downloaded are temporary files, so it's likely they weren't saved when you switched. You wouldn't have double the files, I don't think. unclick the 'offline' playlist option, then turn it back on. Once on wifi and Spotify open, it should sort itself out and download the playlists.
Guest, I have a big favor to ask you. We've been working very hard to establish ourselves on social media. If you like/follow our pages it would be a HUGE help to us.
