Five times listen, I think its enough for serious review. 
So, what we have here? Neil and Liam always knew that they gonna bring at least one album together. So, we can talk about spontaneous in unspontanousity. And, recording music album spontaneously is definitely not always a good thing...
Prelude/Island of Peace - I am not sure should I call this a serious "song"... if it is I should review it as one - as gift for somebodies/sons wedding ideal thing, beautifull, wonderfull. For song on album and published? Hm, I could be harsh and say that for song full of "cliches" like - safe harbor, welcome, together, together, together is no place on music album... 
Meet Me in the Air - here we come on solid ground, nice and calming peace of music work, lovely, but not too memorable..not sure if second place on album suits best...and together with Where is my Room and Back to life only three songs in which I have feeling of together Neil and Liam work, rest of album are Neils songs and Liams songs in my ears...
Wheres my Room - this is a typical showcase of song in which performers have much more fun than listeners. Unneceseraly more than 7 minutes long song, which I skip each and every time after Neils line "show is over..." And here starts my problems with Neils singing on this album which is far under his level, the way he sings is just...not good...
Anger plays a part - Lovely Liams singing, full of emotions, easy gets to listener...But, without stronger rafrain than "I know that anger plays a part...".its just a good song, nothing special. And, next problem is - when you have interesting song like TNT for Two in which singing takes almost 4 minutes and than you have chanting in the end more than one minute, its a wonderfull thing. When you have singing about 90 seconds and than 90 seconds of TU-DU-DU-DU-DU, its just lack of idea and inspiration, which ends in my case 30 seconds after. For this again I dont blame Liam, he probably gave his best, but Neil was the one who should come with some strong refrain, put some salt in this song...
Listen - unfortunately I didnt hear this song in earlier version, but this Neils talking/singing is just iritating and doesnt serve a purpose. Song which otherwise could have been Pour Le Monde vol.2, turns out as avarage good song which (will) never get its potential.
Any other Way - Again beautifull and charming Liams singing, with perfect production and arrangments gave one of the best songs on this not too rich album... It has some beautifull old vibe, but in modern new way...beautiful song..
Back to life - was on the first and is one of the best songs in this son/father era. Neil at his best (perfect singing), Liam in backup, interesting arangments, all in all very good song.
Hiding place - weakest spot on album, again in Neils directing - boring, self important song, not going anywhere., lack of focus. In time of M. Froom it would probably be teared a part...shouldnt be in anyones album...
Ghosts - again fantastic Liams singing (I dont know how he manage that) on one of the most interesting songs on album. Refrain is fantastic and its really shame that this song wont grab any glory wider than between us few fans- 
We know what it means - far better than Hiding place, but again little boringness in Neils directing... and way too long, last two minutes are totaly unnesecary, always skip after 4 minutes of it.. in time of CH it wont be on A side definitely...
Hold her Close - cream comes in the end, so Liam gave us special plesaure in the end of this album. Beautifull song, perfect Liams singing, only one from this album I could put on some wide best of Neils work ever. Altough I have a feeling its only Liam song, but ok...
All in all, what we have here is - extremely fit Liam and extremely unfit Neil. So, results are also mixed - songs in which Liam had stronger role are better, and opposite. Next problem I have with this album is that I dont have a "Finn Brothers" feeling - two men together have one song/album. In only three songs I have that feeling here, in 8 I have feeling that Liam has his songs and Neil has his (more or less but weak) songs. If you admit a fact that Neil is more talented musician with higher potential, and he is the one who is extremely unfit in this record, I honestly doubt one can be too much satysfied with this record in whole.
