I don’t think I could tell the difference between lossy and lossless compression in general anyway - even with great headphones, MOST of the time lossy is good enough. But if you need better, they are planning to offer it, for a price.
That does make me curious - what does it actually cost them to stream the higher quality music? Double the bandwidth? But what percentage of the total costs to them is that anyway, vs interface and licensing? It doesn’t seem like it should change the price much, but it has on other services. TBD here.
