ICloud Drive vs iTunes Match questions

Question

So I have been looking into different ways of having my music accessible throughout all of my OS devices. From what I have seen, I can either purchase a subscription to iTunes Match, or I can just purchase additional iCloud storage. Now just for the sake of my music, I would need to purchase a 200 GB plan, costing me about $50 a year, therefore the iTunes Match subscription would be the cheaper alternative at $24.99 a year. However I do have a couple of questions regarding both options.
Ideally, what I would like to do, is to be able to open iTunes on either my MacBook Air or my iMac, or the Music app on my iPhone or iPad, and be able to access and play any song in my entire collection. Also, syncing of playlists throughout my devices is something I desire greatly.
Now that OS X Yosemite is out (all my devices are either running OS X Yosemite or iOS 8), I understand that file sharing is made much easier. So this led me to think that maybe I should purchase additional storage and store my music in the iCloud Drive. But here is where I start needing some clarity. Suppose I open iTunes or the Music app on a device. Will my entire collection be visible through the app(s), or would I have to access iCloud Drive and play the files from there? Also, assuming that my entire collection can be seen via the app(s), will any playlists that I create be synced? Also concerning the iPhone, if I choose to play a song, will it get downloaded from the Drive onto the device, taking up internal storage, or will it get streamed? Is there, perhaps, a way to have these app(s) continuously sync their libraries with a specific "Music" folder on iCloud Drive (with playlists being synced)?
From what I understand from iTunes Match, all of my songs that are matched with songs from the iTunes Store will immediately be made available to me in my iTunes Library for playing. Now the songs that do not get matched: do they get uploaded to the storage that is provided by iTunes Match (25,000 songs), or do they get uploaded to my iCloud Drive? Are the songs that matched included in this 25,000 song limit, or does it only count the songs that didn't match? Will iTunes Match sync my playlists across all devices, regardless of which device the playlist was created on? Also, on the iPhone, same question as before, will songs be streamed from the storage that iTunes Match provides or will they have to be downloaded to play?
Based on how I want to be able to access and play my music, I'm inclined to think that maybe iTunes Match is the better (and cheaper) alternative? If simply using the iCloud Drive is good enough, then I wouldn't mind paying the extra amount for storage because I'm sure I'll be taking advantage of file sharing even outside of music. iTunes Match also has the ad-free iTunes Radio which might be cool too.
I'd love to hear what you guys have to say about this or if you have any better methods of keeping all music files organized and synced across all devices, then I'm all ears.
P.S this is my first post so sorry if it's lengthy.

Answer 1

ITunes match does not use iCloud Drive to store music. if you want to share music with all your devices, you should purchase iTunes Match. ICloud Drive provides storage for other non music data and you have 5gb free - you can purchase more if required.
