How do I change the album art of songs?

I downloaded this album and all the songs have the picture of the release group which I wanna change, anyone have any idea how i should do it?
Answer #1
You can do that using music players, for example in iTunes you need to select a song, right click on it–>Get Info–>Artwork. There you can delete the preselected artwork. Good luck mate ^_^
Answer #2
You could use Media Monkey Gold v3.0.1.1127

Once the program is installed, locate the folder that has the album and then right click and select download artwork and it should check the various international Amazon sites for album covers for the tracks and then pick the one that matches, simple enough.
Answer #3
Tag&Rename is a good app for get tag info and album art:

Answer #7
what program is this? itunes?
go to google images and find the album art that you want – save it to my pictures.
select all the songs, right click > get info, double click the square box (your album art), navigate to the location where you saved the album art you want and select it.
itunes will replace the existing album art for those selected songs with the new image.
