I've been an avid Spotify fan for quite a while, but it's always irked me that none of my playlist songs are detected in the app. I manually add/remove music from my phone rather than sync, because I find it easier and less of a hassle. I know Android has, built-in, a way to get information for all media files on the device. Is there a way for Spotify to use that function and match songs to playlists by id3 tags, similarly to how the desktop client does it, or possibly just have a "local files" section in the app?
(I did send an email to support as well but thought I'd post it here also)
To demonstrate: on the left is Spotify showing greyed-out tracks ("unavailable") and on the right is Poweramp showing those exact same tracks available to play.
edit: sorry for slightly bad quality on the images, but they're natively 1080x1920 and I didn't think it'd be a good idea to post them full-size.
