IPod touch 5th generation 16 GB is having syncing issues

Question

I have been encountering problem after problem with syncing music on my iPod touch. It's crazy how something that should be simple and quick, is now a pain in the *** to do. I'm trying to simply sync music from my iTunes library onto my iPod touch, and every now and then, for some weird off-the-wall reason, it gets stuck on this "waiting for changes to be applied". Now I've seen other people on here who have encountered the same issue and they're getting like 6 to a dozen step answers that all involve ERASING or RESTORING your entire data JUST to get rid of such a dumb issue like that. Well, sure enough, I did that (or have done it. At least 5 times now to be exact)! And it always seems to fix the issue TEMPORARILY. It'll sync just fine for 3 to 4 weeks just fine after those weeks are up (oh here we go with this **** again) I have to go through the process of restoring my entire iPod and setting the factory settings up all over again. Then it'll sync again. For about 4 weeks, of course. Oh, but now, yippee!!! Another issue!!! Now that the same "waiting for changes to bs" popped up, I did the same thing. Restore the iPod, set up the factory settings, select my last backup. Oh, but now, NOW I hook the iPod up to my computer to sync and it says that it doesn't have enough free space to sync the SAME **** THINGS THAT IT'S BEEN SYNCING FOR THE LAST 5 TIMES THAT I HAVE WENT THROUGH THIS PROCESS!! I had around 1650 songs, PLUS four apps and it synced those and still had EXTRA store of about 200 MB or so left. But now all of a sudden it tells me "You need 500 MB (I don't remember the exact amount) of free space to sync". OH REALLY?! So basically it needs extra space to sync the same thing it's been syncing just fine for the last five times I've done this?! Whatever. FINE. So I remove the 3 big apps out of the 5 and now, OH NOW, ANOTHER PROBLEM!!! Now, I delete those 3 apps, and it tells me I need 700 MB or so in order to sync!!! Remember when it said it need 500 MB in order to sync like I said above? Yeah. So basically, it's going backwards. Now, I delete all 5 of the apps along with about 15 songs: and can you guess what it does? NOW IT TELLS ME I NEED 950 MB IN ORDER TO SYNC!!! THE MORE ITUNES DATA I DELETE TO GIVE IT SPACE TO SYNC, THE MORE SPACE IT NEEDS IN ORDER FOR IT TO SYNC!!! JUST WHAT IN THE BLUEST OF BLUE HELLS IS GOING ON WITH THIS ITUNES??? It's just PROBLEM, after PROBLEM, after PROBLEM, after PROBLEM ever since I've used iTunes. And really all I want to do is sync some music onto my iPod. Why does that have to be such a pain in the ***??? Any advice would be awesome, especially if you're experiencing the very same issue as me; which I highly doubt because it's been a pain in order to find anyone on this site with this issue. Appreciate it.

Assuming Windows, have you tried:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or              
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
You say you have iOS 7.0.6. If that is try update to the latest, 7.1.1
