It's like whoever wrote this hasn't really listened to many of their albums. Monster is pretty far from a straight rock record, and Up doesn't sound like anything else released in 1998 (except for maybe Moon Safari, but that has more to do with the 70s electronics), Some of his comments are perplexing. The list is OK, though. I think the top six are all pretty much equal, and any could be my favourite on a given day.
Because I'm bored:
1. Reckoning
2. New Adventures
3. Murmur
4. Document
5. Lifes Rich Pageant
6. Automatic
7. Collapse Into Now
8. Up
9. Monster
10. Fables of the Reconstruction
11. Green
12. Chronic Town
13. Reveal
14. Accelerate
15. Around the Sun
7-10 are all pretty much even, I think. If Up had 10 instead of 14 songs it would probably own the number one spot. It's just too long and slow, but the arrangements are incredible. That first guitar break on You're In The Air is amazing. I'll never forget the first time I heard it.
Reveal has some poor songs, but the first four songs are as good REM ever recorded, and I love Chorus and the Ring. The production is generally lovely if overdone in spots.
