if it does on same songs, it may been a compatible issues, other it a issue, you should submit on the SK-Jukebox forum.
Im have to say I respect jukebox authors out here, because I are developer of my own jukebox software. So I would not comment which software is best. It a matter of personly chooise and what controls you have.
I can conly only recommered to download demo and download SK-Jukebox to test them out.
In MultiJuke example (my own) it use a another control screme than both two, which can been god and bad for some. It by design, since I did go a bit difficent way....
