New Order WFTSC question (japan-release)

[joethelion]

ok - so on the US iTunes store, they have the Japanese release of WFTSC

so on the this release, I know that there's the song "Krafty" in Japanese, and I've already bought that track

...but...

A lot of the other tracks have alternate titles, are the songs themselves different? or are they just the names of the tracks themselves? I can't tell much difference in the samples, and I don't want to end up buying the album again, only to discover that the songs are exactly the same

for example:
Who's Joe? (Lordsy) 5:43
Hey Now What You Doing (Road to Ruin) 5:13
Waiting for the Sirens' Call 5:39
Krafty (Album Version) 4:33
I Told You So 5:57
Morning Night and Day (Pop) 5:08
Dracula's Castle (Minidisk) 5:37
Jetstream 5:21
Guilt Is a Useless Emotion (Fast Synth)
Turn 4:33
Working Overtime 3:27
Krafty (Japanese Version) [Dry Vocal] 4:35
Krafty (The Glimmers 12" Extended) 6:54
Krafty (Phones Reality Remix) 7:07
