British digital music startup MusicQubed is on the expansion trail. Having launched chart downloads service O2 Tracks with mobile operator O2 in the UK, it’s now rolling out a similar app in New Zealand with Vodafone’s local subsidiary there. The service is called Vodafone Music, and it promises subscribers downloads of “70 full music tracks including New Zealand’s Official Top 40”, with playlists updated every day with new releases. Users can try it for four weeks for free, before paying a weekly subscription fee of NZ$1.50 to continue. Vodafone Music is also not just for Vodafone customers, although those on other networks pay a bit more and can only get a two-week trial. After the launch popped up in our RSS feeds this morning, we suspected MusicQubed’s involvement due to the format, but following the trail to the iOS version’s App Store listing provided confirmation: the company is listed as the app’s publisher.
