V. 3.0.0.11 made the app finally usable. I now can actually play songs and it even recognize wma lossless files. But they're still some issues.
1- The app can't recognize the album art on my wma lossless files (I don't know if it can't read embedded lyrics on this files too)
2- The previous version showed the album art properly (even if it wasn't able to play any music), but this version can't render the album properly, it just look weird.
3- The live tile is amazing, changes instantly when the song changes, and the medium tile does the job good, but the large tile looks bad with that low-res album art (and this is more a suggestion. I don't know if the system allow this with the instant change, but the flip effect just doesn't seem to be appropriated for music, maybe a style that shows the name of the song above the album art without having to flip would be better).
4- On the music library, when I select a letter, it takes too much to show the alphabetical grid.
I guess that's all. Great job, in this state your app has more functionality than any other player on the store, and you heard all the suggestions we had made you. I (we) really appreciate that. You are the kind of developer I want to support. That's why I bought your app (the previous one that had ads) and that's why I want to contribute with the translation into Spanish. When you have any time to discuss this, contact me.
Saludos.
