Q: Why can't I have all my iTunes on my new phone (6s) ?

The most likely cause of this problem is that the songs haven't been downloaded or transferred into iTunes from your 5S.

I would plug in your 5S and then click sync; if it asks if you want to transfer purchases, click yes.

Now when you plug in your 6S, all of the content should be iTunes, and all you have to do is sync again. (This is all assuming that the sync settings are the same between the 5S and 6S) What I mean is, if you told iTunes to add 77 albums to the 5S, but then changed the settings to only upload 35 albums, it will only add 35 albums to the new iPhone.

When you plugged in the iPhone 6S, did you restore from an iPhone 5S backup? If you did, the devices should mirror each other as long as you have a current backup and are not using and old one as your point of restoration.

Yeah that's not so bad!

As far as your music goes, if they are song purchased through iTunes, you can redownload them free of charge.

If your old iPhone has all of your songs you can get them into iCloud using iTunes Match. iTunes Match looks at your music library and uploads all songs not purchased through iTunes into iCloud. This makes your entire library accessible from any of your devices, assuming they are all logged into the same Apple ID. I have not used it personally but according to Apple's website you can enable iTunes Match from your iOS device.

The only other way to retrieve your music is to buy third party software that will transfer music from an iPhone to a computer.

Best of luck

When you do get access to a computer see Recover your iTunes library from your iPod or iOS device to extract all of the media from the 5s.
