I'll join the fray on metadata too. My initial work with digital files was burning .WAV files to iTunes which worked fine until I decided to move them to another drive on my PC. Somehow, I borked the the transfer and the path to the metadata got fubared. It took me quite a while to manually reconstruct the paths so I had albums and artists rather than single files named 01-Take Five and the like. Twasn't fun. I've been using FLAC ever since and convert to 320 .MP3s for my car, which I dump on a thumb drive and shuffle play via a USB. But that may change too as my car unit software only recognize 100 files and is far more cumbersome than my phone via a Bluetooth FM transmitter to the radio. My daughter bought one of these KM18s for under $30 for my wife's car which lacked even an Aux input and it works VERY well.
