The new reality is that most people listen and discover music on their phones.
I decided to commit to Mix Link because of the one time fee that they offered. the other services out there either only have a subscription model or are free but take some time to understand and implement (If you think about it you're trading your time to correctly implement the free option, so it's not free at all.).
To get a competitive edge, you need to adapt to the new reality of the the market. Bouncing your masters or mixes manually to your phone to check the translation is such a time waster I can't believe I didn't know about this service earlier.
The only thing that I would criticize is that latency issues do happen from time to time when using it, but they are so minimal that they do not severely interfere with your workflow. I would wish there were an option to send the barcode that you scan to access the app to a friend, for collaborations. Currently that isn't possible because it only works if your Computer and your phone is on the same network.
Other than these nitpicks I endorse this product fully.
