I've got an idea for you...
But I have a feeling that It's going to REALLY pissoff your die hard fans. If you are still having a writer's block, then maybe you need a break from all this! Take a week or so off, or until you find something that inspires you once again to make a song that will top your previous stuff (if that takes less than a week). The downside is, well, that all your fans will have to wait an extra week for your latest and greatest.
Just a suggestion, even though I KNOW I will get yelled at by some hyper-caffinated coke head with an inferiority complex who can't stand to wait any longer before whacking off to your AMAZING songs. LOL that's a joke people!
Good job on all these demos, and i think that Melo 16 should be called "Flight of Fantasy".
