I'm not trying to discourage you, but for me demo tracks are pretty much worthless, at least as bonus tracks on an EP. They can be fun, but I do not find them interesting enough to pay for them. There are a few bands of which I'll practically buy any release, including singles and EP's, but as far as other bands go, I only buy EP's, if they offer valuable extras, like non-album tracks, many live tracks or even a bonus DVD (like Delain did recently).
