You can use MusConv to transfer songs between apple music and spotify. I've been using it and i think it has been the easier way to transfer playlist from one to another.
Can you hear the difference?
Try this and see if you can tell the difference between lossless files and compressed. I got two out of the three correct yet I missed one even with my "young" ears. I'm using Sennheiser HD 650 phones on a modified MF headphone amp. The purpose of this fun little game is that Spotify is doing some testing with loss-less music. It's just something you can have fun with, would be interested in what this forum scored!
