That's what I have been doing. There are many more that I can tell aren't gapless because the breaks are senseless. For example, I was listening to an opera. The track ended while the soprano was holding a note. There was about a one second gap before the second track started and it began with the tail end of that same held note. Takes you right out of the moment and does a diservice to the artists. No excuse for this, in my view.
I think the only reason they are getting away with this is because apparently all the streaming services do it and nobody has any interest in fixing it. If all users were to cancel their subscriptions at the same time and refuse to resubscribe until the issue had been fixed, they'd have to do something, but I don't see that happening. However, if one were to take a stand on this (a new service or an existing one) they would clearly have an edge on their competition. Especially if there were some real consequences for streamers who say their content is gapless and you find out that not all of it is.
