Assigning album art for songs from gallery (not music players)

Because of the blurry album art we cant enjoy cover arts... So here is the idea. We can assign jpeg, etc. Files from our storage to a song so when the song plays the assigned picture will be shown instead. This way KWLP will load the album art from the gallery instead... Because music players lowers the quality of the images resulting in blurry images

One by one assign is really a hassle so we can assign images to album names or author names so if a song in that album name or author plays the assigned pic will be loaded..

(bitmap custom path)+(album, song name)

Is this possible?
