Cover art replaced to all the same when imported into android. GS5 ATT

[AC Question]

I have lots of music that aren't in specific albums. and when i import them to my computer, the cover art on all of the unalbum-ed songs get replaced with another album cover that isn't their own just because the device thinks it should assign a uniform cover art to tracks that have no album. Now all of the tracks look the same. How do i fix this?
