The problem with me is that I want high quality music on my phone (and I listen to it with high quality headphones all the time). Like, nothing except 320 kbps MP3 files and occasional lossless files that randomly find its way to my library. I have an Android smartphone that only supports memory cards up to 32 GB in size. It's a pain. I can't even get 1500 songs properly (keep in mind that the music is not the only thing that I have on the SD card, there's also my book library and some photos). Streaming them in that quality for two to three hours in per day on average would take a lot of data.
