Like many people, I am a big daily user of Spotify and found something that could be improved. When you want to add a song to one of your playlists, it is currently impossible to immediately place it where you want in the playlist (especially on the mobile app). Added songs always end up at the end of the playlist by default and it’s just not optimal to then access the playlist, click edit, and chose a position for the song.
New default : Add to Playlist --> Chose a position
Settings (Song Position in Playlist) : Default (at the end) vs Chose position in playlist
