The answer is almost perfect for my needs. The spotifycodes.com page is easily understandable and well-crafted! Yet another thumbs up for Spotify.
I've got one more question though - when I create such Spotify Code and simply put it on a T-Shirt (without any other trademarks - not even album title or band name, that may be protected by copyright law) - can I sell such T-Shirt without breaking Spotify's copyright laws?
For example I was interested in creating such code for a Linkin Park song, Nobody Can Save Me (uri: spotify:track:3dJj6o9o1fRgrojWjailuz). Once the code is created, I would like to download it and then print it on a T-Shirt.
My question was if I wanted to sell such T-Shirt (with Spotify Code), am I allowed to do it without breaking any copyright laws. In my example no song or artist name would be printed on a T-Shirt - just a generated Spofity Code (and also some custom text maybe, not connected with song or artist).
I was actually reading out your conversation with @TomoLV.
I would actually like to know why aren't we allowed to print specific artists/albums? I can't see a negative point because, one, we kind of advertise that artist and 2, we also advertise Spotify as a platform (being the only platform that can actually scan the code). Does it have to do with the fact that we are making money out of that?
