Few days back I posted a question what makes a song idea good one? I guess this is the best answer I can come up with. 

A song idea is good if you get excited by it. 

I think that’s what people call “fresh” when they describe new songs and sounds they are working on. 

I think that some sort of excitement is what drives me to write music. It’s about learning and researching new stuff all the time. 

Here’s one old riff though. Good stuff even though it’s not that fresh for my ears anymore.
