I guess I abused the free trials with Tidal and got *BANNED* - meaning, I they won’t even let me pay for the service! Never liked you anyway. So I pay my $20/mo to Deezer, whose app is sort of glitchy, but it’s basically a good service. I find it’s hard to get to CD quality sound from streaming even with a lot of extra $ spent in DACs. It sounds good, but not as good, even if the files are bit-by-bit identical.
I'm quite happy with Tidal. On a side note, Spotify pays an artist 1/16 of a cent for every track played. Which doesn't like much until you start multiplying that by the thousands and tens of thousands, etc. 
I hope Tidal stays afloat and becomes profitable. I like MQA titles. Perhaps Bob Stuart of Meridian can throw them a loan. He makes alot on money from MQA licensing and I would think he stands to lose if Tidal folds...
Alas, as in the past, the musician gets the money last. 
So, basically TIDAL is bleeding cash and using the artists' already earned royalties to fund the company. This will probably be the undoing of TIDAL's current ownership group. They won't be able to pay the accumulating interest on six months' worth of unpaid royalties--together with the legal bills they will owe for defending against the breach of contract cases that will be filed. They may also be liable for the attorneys fees the record companies and artists incur in collecting their earned but not paid royalties. The one asset they will have to pay their debts will be their equity positions in TIDAL. It is a good product that will probably survive with a different mix of ownership.
In December 2017, someone reported that Tidal may only have enough cash left to last six months.  I searched Google today and found no information on the financial condition of Total Streaming.   Are they really in trouble?  What is the real story?   Are they for sale?

The above post reports that Tidal has serious problems in various areas.   Others have reported that "Tidal’s subscription numbers have been disputed, but estimates put it between 1 and 3 million, much further behind even Apple Music, which has 30 million. With no turnaround in sight, or change in strategic direction, some analysts speculate that Tidal will eventually SELL itself to one of its rivals, hoping to buy their subscribers and exclusive content on the cheap".

I am a Tidal Streaming user and like it very much.   Its sound quality is excellent, its album selection is great for me and I enjoy the MQA selection.   if Tidal goes out of business, my Aurender will support QuBuz when it becomes available in the USA (but no other non compressed music streaming service).  

Based on many Audiogon posts, many Audiogon users are Tidal customers.  I hope that Tidal Steaming continues and doe NOT go out of business.
