@TopCat, if you want to listen (and potentionally download) to the others in 256 kBit/s MP3, the BMG website has them. The demos are - being 256 kBit/s - pretty decent until the FLAC/WAVs surface. Unfortunately, they seem to move websites right now, so it keeps redirecting me to the German website (which can be toggled to English in the top corner), so if you want give it a shot,
here you go. They are always sorted as the newest, so scroll down to the very end and you will find what you are looking for. Happy browsing
Please note that some of the ESL tracks are differently managed when they went to that website compared to their original release (let alone the different covers). The real covers, albeit pixelated a bit, can be found at the
NICHION SOUND LIBRARY. I recommend you to use the Wiki to help you sorting out the ESL catalogue. Don't worry, it's not completely messed up, but they re-managed some of their albums apparently and tracks have changed (merged into other albums), so it gets a bit confusing. Look out for the "later renamed" notes on the Wiki to get the real picture. The Wiki has the actual releases - the correct ones so to speak, just like NICHION.
If you need help to download these demo files let me know (it is quite simple).
