Hello Spotify Community.
So about a month ago, I bought a Samsung 128 GB Micro SD Card for my Galaxy Note 4 (Running Android version 4.4.4). After I put it in (I was using Google Play Music at the time), I would download songs on Google Play, and then when I played the songs, an error message would come up that it "couldn't play the song I requested". If I streamed the songs, they would play, but I think the downloaded songs were corrupted. So, after my annoyance with Google Play, I went over to Spotify, like I used to. Now, more problems came up.
Yesterday, I tried downloading all of the albums in the "your music" section. It seemed to finish downloading in a day (Slow downloading times). So, I went to play an album and the app just became incredbly slow. And it wouldn't play my music. Then, I tried playing another album, and it wouldn't play. And to make it worse, it started redownloading the album that said it was already downloaded. So, I restarted my phone, and ALL OF MY OFFLINE MUSIC DISAPPEARED. So, I reinstalled Spotify and I'm hoping it doesn't happen again. I have a slight suspicion that it has to do with the SD card. The card works fine. My photos and videos are transferred easily. I have reformatted the SD card, and factory reset my phone, and reinstalled Spotify many times. Please help. All of this downloading is making Spotify incredibly slow.
