I have roughly 30-35 gigs of music. Before I purchased the iPhone 5, I always purchased the 32GB version and just carefully managed music on my phone. It was a pain to decide what music I could live without on my device. With the iPhone 5, I grabbed the 64GB version and finally was able to store all my music and no longer worry about storage. I noticed today, however, that I've got about 2GB of free space remaining and I imagine when new apps come out for iOS 8 that the space will be gobbled up quickly. So my two options are iPhone 6 with 128GB or 64GB. If I go the latter route I save $100 but I will go back to needing to manage music soon. I do have iTunes Match and a Spotify subscription so maybe I can just live with less music actually on my phone. This would only be an issue when on a plane (I don't travel a ton for this to be a big issue). So those of you with huge music libraries, what do you do? Lean on streaming or buy as big of storage as possible?
