If its cloud-based music, yep. If it's music files on the device itself, then possibly not - mp3s can include album art in the file itself : http://techie-buzz.com/music-tools/embed-album-art

Pretty sure it doesn't use data. I've pulled up music while in airplane mode and the lock screen still displays the artist image.

It would just depend on if the file had the image already imbedded or had already been fetched at some point, so the answer is "it might" - if it doesn't have the artwork already, it's got to get it from the internet...
