I am one of those people who would carry around 2TB of music if possible. In fact, the large capacity was the only reason I had(rip) an IPod Classic or Video.
I do not care about library update for two reasons.
1) It is extremely difficult to program such a feature for so many different file-types. Alone FLAC has a few versions of tagging.
2) Updating libraries is slow. I do not need that feature, but I would never say here to James, that he should stop offering it, just like some members here do with the OTG feature. To make it short. I browse by folders.
If it is possible for James to implement the possibility to use an external hdd and dac via USB, I hope he will do it.
