How to transfer itunes music from mac to mac, explicit songs not syncing to iphone?

I got a new mac and i used a flash drive to transfer some of my music, but is there a faster and better way to transfer any of it? It won't let me have some of my songs because i bought them under different itunes accounts. Is there any way to fix that? Also, my explicit songs will sync to both my ipods, but not my iphone. Why is this?

Go to file explorer >> iTunes Media.
Get all your media files from iTunes (old MAC) like mobile apps, photos, music, videos etc.
Collect them and paste in the respective iTunes Media folders into your new PC.
These way you will get all the data without missing anything from iTunes.

In that case, you can make use of your iPod. Download one 4easysoft iPod Manager, which is a wonderful transfer, then use it transfer files from iTunes from one Mac to iPod, then connect the iPod to the other Mac, open the software again, and then send the msuic from iPod to mac.

  • Why is iTunes not syncing some of my music? I have 2 albums of Red Hot Chili Peppers, Dani California and Greatest Hits, and when I sync them to my iPhone, I tap on Red Hot Chili Peppers and it only comes up with Dani California and non of the others appear. Why is it doing this?
  • Why can't i download explicit songs? I have an iPhone 4 and an active iTunes account. I have downloaded explicit songs before on this account, but am no longer able to do so. I can't find a setting on my phone that was changed, and have not been able to identify what caused the change. I'm able to download non-explicit songs, if that has anything to do with the problem James mentioned restrictions. Where would i find that section of iTunes
  • Why aren't my songs from iTunes syncing to my iPhone? I have 1365 songs in my iTunes library which I can play. But only 1260 songs are transferring over to my iPhone. I just got a replacement iPhone about 4 days ago so I'm not sure if that has to do with anything?
  • Syncing iPhone songs onto iTunes? Okay so what I want to do is make ringtones on my iPhone 4s. But in order to do that I have to sync my iPhone to iTunes. Which I haven't done yet with my phone.

So is there any way to sync the songs and all the apps and media from my phone onto itunes on my laptop?
