I just wanted to let you guys know that on the "Play Next" queue, if I click and a drag a song to rearrange the order, sometimes a completely different song (usually the one that is currently playing) will replace the song that I just tried to reorder.
As a side note, I also have a large (20,000+) iTunes library, and my VOX player tends to delay when I select an album, artist or click on a song. I'm guessing that it is loading the song, since there are so many songs and it has to find the file through the iTunes media file, but then again, maybe you guys have a different method of retrieving the songs. I don't know if this is something where you guys could optimize the sorting algorithm, but thought I'd mention it.
I'm running on Yosemite Beta (Version 10.10)
Love your software, and I hope that it can progress to become the default player across many computers.
