2 months ago, I didn't realize this EP existed. I was shocked to see it listed for $100+, even $200+ Since then, I got into some bidding wars for it (some lucky bloke got it for $8.50 - brand new!) before I got my hands on it at a price that fit my pockets. Keep this little tale in mind when shopping for it. As to the EP itself - for FLips fans, it is worth $200+!
"Bad Days" sounds just like the "Clouds..." version (but that's okay, that horrible batman movie ruined this song for me anyway -my fault for watching it) and I believe that the same version of "...Waterbug..." is available on the "Turn It On" single, but everything else here is unavailable elsewhere as far as I know and is pure GOLD! "Chosen One" and a slightly harsher version of "Slow-Nerve-Action" (which ends with a short, instrumental hidden track) are worth it alone. Wayne Coyne has a certain sadness in his voice that doesn't depress you, but kinda touches you, especially in the beautifully clumsy version of "Little Drummer Boy".
Bottom-line: Get it, but don't hurt yourself in the process.
