YouTube is postponing the launch of its long-rumoured subscription service as it refines and tweaks the offering. Billboard reports the delays are down to the company wanting to “get it right” straight out of the gate. The issues appear to be down to the UX and UI rather than licensing – with Billboard saying parent company Google had cleared the requisite licences with the major labels a year ago. Some of the stumbling blocks are what to present users with when no official video exists for a track; this could be a static image with basic information about the song/artist or possibly an “art video” that uses dynamic pictures or other stock videos. There are also, according to the report, concerns about how to migrate young consumers – long used to YouTube being a free platform – into a subscription environment and doing so in a manner that does not pull the rug from under how it currently reaches over 1bn users a month.
