Is there any trick to getting Mixtrax to analyze songs on the SD card faster? I have a 32gb card with 6000 songs, and after several hours only have 120 songs analyzed. It appears it only does analysis while playing from the SD card (even with Mixtrax off, I think), but not if you're listening to Sirius or anything. I really wanted to use it during this long road trip I'm on but it's just not happening.

Are you sure the card is formatted correctly?

It's 32gb formatted as ntfs. It plays fine otherwise.
