I am stunned at how this awful application has trashed my iTunes library. I ran it a few times and dragged and dropped a few tunes from iTunes into it, it sussed out the tempo correctly for a few songs and wrote the BPM tag back to iTunes nicely. Great!
Then it started slowing down and I could hear my Lacie FireWire drive start to make weird noises. It was chugging and make a 'chk, chk, chk, chk' noise like a ticking clock. Next time I opened iTunes it was all screwed up, permanent beach ball, ticking clock again from the FW drive. So I ran Disk Utility and Repair Disk on the FW drive and it seemed to fix the drive okay. But now a good percentage of my 23,000 track iTunes database has been wiped out, and many, many more have had their database links broken. The files are all in a folder called lost+found and though I've been able to salvage a lot, a lot more are permanently wrecked.
How dare they make such bold claims about this app. Christ I am so mad, I could spit. It's taken me nearly six years to build up that library and Ask the DJ has wiped half of it out in about 10 mins. These people have a lot to answer for. I am still awaiting a reply from their support department.
