This used to be something I would attempt to do all the time. ATYCLB and HTDAAB were my favorites to mess around with.
Can't remember the tracklist I came up with for ATYCLB completely, but I think it went something like this:
Beautiful Day
When I Look At The World
Kite
Elevation
Stuck In a Moment You Can't Get Out Of
Stateless
Flower Child
New York
Walk On
The Ground Beneath Her Feet
Grace
(You can substitute in New York(Nice Mix) and Elevation(Tomb Raider Mix) here, but it flows best sonically using the album versions, imho.)
HTDAAB I can recall pretty much exactly, except City Of Blinding lights and Smile may have been switched in the order:
Native Son
Miracle Drug
Sometimes You Can't Make It On Your Own
Love And Peace Or Else
Fast Cars (Jacknife Lee Mix)
City Of Blinding Lights
Smile
All Because Of You (Alternate Version)
Crumbs From Your Table
Original Of the Species (Single Mix)
Yahweh (Alternate Version)
Mercy
(Here you can substitute in All Because Of You (Single Mix), Fast Cars (Original Version), and Yahweh (Album Version). The only weakness I feel here is that Mercy does not have a real ending, it just kind of fades out which I suspect was something they planned to change if they decided to use it in the future. But I love the song too much not to include it and I feel overall it provides a very fitting conclusion to the record. Again, this is just my opinion.)
Anybody, please try these out and tell me what you think!
