The release and update of songs within Spotify is dependent on the labels in charge of those songs. Spotify releases songs as soon as they get them...you may just have to wait for a bit before being able to listen to them.
So what I don't understand is why the songs from yesterday's episode of glee aren't on spotify. I know it has something to do with record labels and whatever but if I remember correctly I got the songs from last weeks episode on the day of that episode. I don't get it, I just want my dang glee songs. Is that so hard to ask. What do I do because this is just stupid. I just want them ASAP, preferably on the day of the episode. Is that even possible.
