GS5 not showing local songs?

Very new to Spotify premium! On my galaxy s5, why don't any of the songs i already had stored (on SD card) show up in the library?

Spotify will only play local files which have been synced from a PC. Please read the support topic here for assistance setting up local file sync: Listen to local files

Make sure that you are on the same WiFi network and Windows & third party firewalls are configured to allow the Spotify connection through.

Another point to note is that sometimes if a track is stored locally & is also available to stream then when you sync to your device it will automatically use the Spotify streaming version but the data from your playlist. If for some reason the metadata such as track length differs this can cause conflict and break the track. In this instance you are best off removing the local file from your playlist on the desktop and adding the track from the Spotify server then re-sync. This should fix this issue.

Thank you, still a little confussed? So all the music i have already stored on the phone cannot be played offline through spotify in the car for example? I need to find it all on spotify (quite a few aren't avaiable) and save it, then download it to effectively replace what i have already?

Correct. Any file already saved on your device will not play through Spotify.

You must transfer those files to a PC, create a playlist then sync to your device.
