Whilst I truly dread to think what Forever 25 will look like (assuming we'll get it), it's really shameful that the true sum of "new" stuff that we haven't heard through leaks in this release is two live recordings and a party mix. We thought Spice 25 was bad, but at least it gave us an unreleased track, two unheard demos and the Love Thing mix which some people did have but wasn't widely circulated.
The thought that this might be all we ever get is so disheartening. One option would be to reissue the Greatest Hits for the 30th anniversary and give us some more breadcrumbs but I don't see them ever doing a "rarities" album because they clearly don't think the material is strong enough. I don't think any of the demos we've heard from the early years stand up to the songs we know and love, but they're still cute in their own right and deserve to be heard. I personally prefer Strong Enough to Feed Your Love, it's madness that they couldn't even stretch to including that somewhere when it's all over YouTube.
