AIFF file format in Spark

[DrMaustus]

My entire library is in AIFF and I do not have any issues with playback. If I do have issues it's with the Spark app itself, in particular on my Mac. Spark acts quirky sometimes. For example, when I select on an album or a track, nothing happens and it just goes back to the main menu. I find Spark works better running on my iPad or iPhone.

I believe this issue is caused by updates to files in iTunes. I notice the same thing that you do, but only after I open iTunes to add files. It is a bit frustrating, but I now make a habit of closing Spark, then making changes in iTunes, and then opening Spark again...and waiting a minute or two for it to "settle" down. After the initial period of Spark finding and indexing the new content, it seems to work fine.
