I have a Macbook Pro running High Sierra from about 2010! Obviously she's not my main computer, but she's a fantastic media centre, with all my music on iTunes, connected to my stereo. Problem is that I am completely out of space, which makes no sense. iTunes has either 204.25gb of music, or 219.01gb, depending on whether you're looking at the iTunes app, or at the system information. The system information also shows 790mb of downloaded apps (the biggest app is 750mb, and doesn't want to be gotten rid of). Somehow a maximum of less than 220gb fills up a 250gb hard drive. I raeslise there are native apps, and operating system files taking up space, but do they really take up that much space? Isn't a 250gb hard drive, where 30gb is completely unusable a bit of a rip off?

If it is just system files taking up space, are there any I can safely delete? I'm once bitten, twice shy on that one; I know that you can't just delete those files willy-nilly. Or are there perhaps native app I can delete. I have literally never used most of them, I just don't know how to delete them.

Because when I say that there is no space left, I mean there's none. Annoyingly it fluctuates, I guess that's depending on what the RAM is doing, but sometimes it says there's a couple of hundred mb left, sometimes it says there's zero.

Another thought is that the discrepency between what iTunes shows, and what the system information reflects the music that's on the hard drive, but not in iTunes. If that's the case, is there any way I can delete all the music that's not in iTunes?
 
Are you running Dropbox by any chance? (It has old cache files that can get huge and can be safely deleted.)
 
This answer is coming to you from a MBPro mid 2012, a wonderful machine!
Given that your 2010 MBPro was initially launched with OS X Leopard there have been a further 7 major updates to bring you to the current High Sierra. Was your current system a clean install? If not you may have many chunks of data scattered behind from previous systems, which could significantly block and slow your system down.
When I updated to High Sierra it was performed as a clean install onto a new SSD. I gave it 2 partitions, one 250Gb for the OS and a second of 250Gb named 'Data' and reserved for downloads, and other general data.
I occasionaly download a new App and place it on the main OS drive, but it doesnt get too cluttered and is currently indicating 168Gb freespace remaining. Whenver I want to delete an App I rarely or never use, I never just drag it to the desktop to delete as that leaves garbage pieces of data behind. I always delete apps with AppCleaner which is a free download and very effective. Well worth a try!
You may wish to flush out unnecessary junk files using Onyx. I no longer use it as my system appears ok and doesn't need it, but in the past on my other Macs it has proved very useful.

204 GiB (Gibibytes) is very nearly 219 GB (Gigabytes), which explains the discrepancy. See this article for an explanation, but in a nutshell GiB are powers of 1024 while GB are powers of 1000. And yes, it's confusing for the OS to be using different units in different places.

Sounds like you're just out of space. You could replace your internal drive with a larger one, or you could move your music library to an external drive.
