If this is legit, we can approximate the full thing. The angle of "The Gift of Music" is ~11,19°, which equals 4:08, or 248 s. Therefore, approx. 22,16 s equal 1°.
Thus, the whole album would be 22,16*360=
7977,6s=132,96min (more commonly 132:58, so 2 seconds short of 133 minutes) long, which is not exactly 2h10min, but fairly close. If you measure each angle, you can convert them into seconds by multiplying 22,16 with that angle. Divide that by 60, and you got your minutes. For example, "Astonishing" is 16,18° and would be 16,18*22,16=
358,55s long, which is 358,55/60=
5,98 minutes (which is 5:59 as timestamp, so just a second short of 6 minutes). I don't feel like measuring every angle right now though.
"A New Beginning" seems to be the longest song and would be
7,86 minutes (= 7:52) long.
"The Hovering Sojourn" would be the shortest song with just
30,36 s (= 0:30)
