What are my options for music storage?

I just want to be able to play my music from my iphone, and store it on someone elses hard drive. I have about 160 GB+ in music, and more than the 25k in songs allowed by iMatch, I doubt that they will ever raise the limit, so I suppose my only choice is to go for one of the pay by gigabite things which would set me back quite a lot.

There are all kinds of free Clouds where you can stash this, if you split it up. I have music on Amazon Music, and several Cloud accounts that came with various programs on my HD. The Amazon app lets me search my HD for whatever folders of music I select, and then I can download or remove things as I wish. That means I can 2-step call down things from a Cloud to my HD, then thru Amazon onto my phone, if I'm changing it All in bulk. As professional career musicians, since 1971, we own so much recorded music - several thousand CDs, tons of vinyl, cassettes, RTR, etc - all in process of digitization, but it will take YEARS - that we have had to bar-code scan and database it all. I carry a separate mp3 player with several storage cards - but I usually will consolidate what I'm carrying, according to what I *need* right then for work. You do NOT have to be like a musical Bag Lady - dragging everything you OWN around with you - as long as you keep really good track of where it is stashed. So - some in Cloud storage, and some in storage CARDS for the player works best for me. I do not need to carry every instrument I own, either, when going to a gig - just what I'm playing *then*. If you were in the music business as long as us, you woudl see that 25K is only a piece of the pie, compared to what others of us own - we just do not need to access it All at the same time. ("You call that a knife? THIS is a knife!"). My adult son is also a professional musician, conductor, and recordist - and HE back us his music files in terrabytes. Seriously. Who raised this kid?
