If you can hear it in your head, then it sounds like it's just a matter of production skill. This is a much easier problem to fix than if youre just drawing a blank. If I were you, I would just get better at remaking sounds. You could get Syntorial, or (to save $130,) you could just remake songs from beginning to end.

What helps me is if i cannot create a great drop but i have a good verse is that i wait awhile. Then i try again but sometimes i try the drop in another key then transpose it back. Also if i cant find anything in the key i try using modes.

I had this problem a long time too. Don't worry though. Finishing tracks will come naturally when you improve your production and song writing skills. Its all about learning as much as possible and then it will come naturally. Don't force yourself to finish stuff.

I disagree. Do force yourself to finish stuff. You will not get better at things you don't practice.

Tracking out your entire song's drums to determine the arrangement actually sounds like an awesome way to teach yourself how to be really creative with fills and single shot percussion, too!

Not being able to finish a track is completely normal, It's been almost a year since I've finished one, but then again, I didn't produce for 6 of those

You need to balance production with someone else so you don't burn your brain out.

It comes with a bit of time and dedication. It took me quite a long time to actually sit down and finish something structurally. What did it for me was a remix competition. The deadline actually helped me focus on it and shut other stuff out. It didn't make me rush it but the looming deadline made me not get too bogged down in certain areas. I had also made peace with the fact that it wouldn't be a masterpiece, but it was all about baby steps, and that was the step I wanted/needed to take to move on. it gives you the confidence to break through what can feel like a brick wall of frustration and 'I'm shit at this' that makes you open your DAW then open iTunes instead. It's part of the learning curve that'll get you towards where you want to be.

A mate once said to me on this subject 'learn from everything you do and try not to be too critical of yourself.' It works, even if you don't know you're doing it!

I'm by no means an expert producer, I'm still a newbie. I read and re-read things that will boggle me for a time, until it clicks, and the satisfaction I draw from being able to understand and apply things is what keeps me going. That counts for all areas of the process. It helps you learn invaluable stuff, too. I can't wait to upload my current WIP on here and have it pulled apart for that reason!

Also trying to start with something other than the intro might help you a bit. The track I'm working on at the minute doesn't have an intro yet, I'll just strip back some of the other parts and make it work, either when it comes to me or whe it's the only thing left to do.

Stuck with it.
