Music Store/Chartbuster
Chartbuster is gone now, it has been bought by DigiTrax, and has re-emerged as KaraokeCloud.
Chartbuster purchasing and streaming subscriptions have been terminated out from under us. I have been fighting to get KaraokeCloud up and running. If it were up to me, it would have been done in June, alas, i am dependent on DigiTrax for their implementation.
When it comes up, I do not know yet if you'll get a free, pro-rated subscription on KaraokeCloud for the remainder of your paid time from Chartbuster, but i'm asking about that.
We've made some good progress in the last week, but i'm still waiting on some things. If you want to track it yourself, see this page.
