This post more or less covers my "thinking process" for how I got into my list of favorite albums.
Instead of taking a time to think and rate these albums based on their merits and whatnot (I can never form lasting opinions in that regard

), I'll just "rate" the album based on the tracks that I most like listening to, singling out the tracks that I more or less solely listen to only when I'm playing through the entire album.
Oxygene - 66.67%:
4/6 - Parts 3 and 6 singled out
Equinoxe - 71.43%:
5/7 - Parts 2, 6 and 8 singled out
Magnetic Fields - 40%:
2/5 - Parts 2, 3 and 5 singled out
Concerts in China - 85.71%:
12/14 - No, there's not a track called Magnetic Fields 1 on this album. Band in the Rain and Magnetic Fields 3 singled out (yes, even Harpe Laser occasionaslly warrants a listen

).
Zoolook - 71.43%:
5/7 - Diva and Ethnicolor II singled out.
Rendez-Vous - 83.33%:
5/6 - I never listen to Rendez-Vous 1 without 2
Revolutions - 70%:
7/10 - Tokyo Kdi, Computer Weekend and September singled out.
Waiting for Cousteau - 75%:
3/4 - WFC singled out.
Chronologie - 87.5%:
7/8 - Part 7 singled out.
Oxygene 7-13 - 85.71%:
6/7 - Part 11 singled out.
Metamorphoses - 58.33%:
7/12 - Hey Gagarin, Tout Est Bleu, Love Love Love, Miss Moon and Silhouette singled out.
Sessions 2000 - 0%:
I haven't listened to this album at all since 2003. However, I don't hate the live version of that one track that was retitled as "Solidarnosc" in the 2005 concert in Poland.
Geometry of Love - 12.5%:
1/8 - While in practice I NEVER listen to this album, the first track (Pleasure Principle) remains the one I've listened the most on the album.
Teo & Tea - 15.38%:
2/13 - OK, Do It Fast and Vintage are the only tracks I listen to on this album every now and then. I've only played through the entire album once in 2007 and that was quite enough for me (no idea if I'll ever repeat this process), and the title track is better live (without the voiceovers), but I never listen to it separately anyway.
In fact, the only instances when I tend to listen to the title track is via
my remix of it.
Electronica Part I - 62.5%:
10/16 - If, Conquistador, Zero Gravity, Rely on Me, Watching You and The Train & The River singled out.
Out of these tracks, I do often listen to the JMJ Remix of Conquistador, the Above & Beyond remix of Zero Gravity and the JMJ Remix of Watching You, but they're not included on the album.
So this way my list of "favorite albums" would come down to:
Chronologie - 87.5%
Concerts in China - 85.71%
Oxygene 7-13 - 85.71%
Rendez-Vous - 83.33%
Waiting for Cousteau - 75%
Equinoxe - 71.43%
Zoolook - 71.43%
Revolutions - 70%
Oxygene - 66.67%
Electronica Part I - 62.5%
Metamorphoses - 58.33%
Magnetic Fields - 40%
Teo & Tea - 15.38%
Geometry of Love - 12.5%
Sessions 2000 - 0%
I wouldn't say it's a definite list of favorite JMJ albums in order from most to least favorite, though. I guess different lists could be made on grounds like "JMJ albums in order of artistic integrity" etc.
I prefer Images over Aero when it comes to compilations (I don't have or care for the rest) and while I tend to listen to Cities in Concert more often than the others, Hong Kong is actually a far better live album.
