I am on my way to work, so I cannot compare waveforms, but I am very sure that Listen to their No and Schiphol Test have some subtile difference and altitude dub sounds like it has a slightly different mastering, but that my just be because of iTunes.
Doris was already mentioned. The EP is also about a minute longer, but again no time to see the exact differences.
Definitely not the same tracks. But also my mind might device me
