This is an excellent mastering program! It is inexpensive and easy to use. However, the biggest issue is that you can only master tracks individually, though you can upload numerous files at once. What this means for you is that it will be harder to get a cohesive mastering across your entire album.
So, if you are working on multiple tracks, this may not be a great fit. But if you are only trying to master a single, give LANDR a try.
