to the original or more well known studio album version.

Examples

Pavement - Grounded (Crooked Rain Demo Version) http://www.youtube.com/watch?v=RiDSr2uq2XU
Always preferred the more sped up demo than the slower Wowee Zowee version.

Smashing Pumpkins - Blue Skies Bring Tears (heavy) http://www.youtube.com/watch?v=dc4GZtkrecA
Completely blasts away the inferior Machina I version.

Blur - Far Out (Electric Version) http://www.youtube.com/watch?v=OVjoIZ4Txqs
How they chose the one that ended up on Parklife over this I’ll never know.

Radiohead - Morning Bell/Amesiac > Morning Bell/Kid A
http://www.youtube.com/watch?v=CPQfiH78XaE

MBV - To Here Knows When (Tremolo EP) http://www.youtube.com/watch?v=lF6mWMCDECE
Always preferred this outro over the Loveless one, and it’s mixed slightly better.

DJ Shadow - Organ Donor (Extended Overhaul) http://www.youtube.com/watch?v=cAjZ0XqZ1aQ
Managed to turn an already decent track to an even better one.

The Fall - Theme from Sparta FC #2 http://www.youtube.com/watch?v=Y-15ScxO07k
The US version has more of an energy to it compared to the UK one.
