Personal Colors for Song Title Background

[PaytonPlz]

When looking through my songs, the little album square always catches my eye. The visual allows me to associate a song to a certain feeling or just makes it easier for me to remember how I felt when I listened to the track. I would like to keep the same art but allow for changing the grey-ed out area behind the tracks title and artist (as seen in a playlist view). Being able to change a track's background box in playlist view to a few different colors would help me associate my music with different feelings and give more personalization. 

This would have no implications to those that weren't interested in this but would give a unique way for everyone to "tag" their music- red for high energy, blue for sad, green for happy. Anyways I love Spotify so so much so thank yall for being so wonderful
