If your looking for a video concept, then I'd say "long time"

If your looking for the next single that 'could' get radio play and possible video rotation, then I'd go for "Clock with No Hands".

Clock with no hands I don't think would really ruffle any feathers.
Solid lyric matter that keeps it in check.

Long time is more a retrospective of things that were and what they are now... would be great for a video concept.

You could intermingle old footage, kinda like an old 8mm film projection against a wall in your parents living room.

Problem with going with this track is that it'll seem more like a lament to what was and not where your going... with your label situation at the moment, I don't think you want to give that vibe to the masses.

I really don't think you should go with 'here I come'.

My honest opinion is that the tempo is too fast and the track does not have that 'hiphop feel' for the masses.
It kinda reminds someone of those hybrid songs between a rock outfit and an emcee with an electronic-type flair to it.

Just my opinion.
