I've wittered on about the difficulty of finding the ideal digital music player before, though I'm too lazy to find the link. I recently picked up a cheap 8Gig refurbed player since it was on offer, and the headphone connector on my current model is going again. Unlike the various models that I've owned previously, this one is based on ID3 tags.
Who thinks that this is a good idea? Even assuming that you have got your entire music collection all tagged up nicely via CDDB or similar resource, how is that any way to navigate your files? The whole folders approach has worked reasonably well on computers for the last few decades. It gives a nice flexibility for people to arrange things how they like, according to whatever idiosyncratic hierarchy and arrangement happens to appeal to them. In particular, it's particularly terrible when it comes to audiobooks and radio recordings: I want to listen to one of these at a time. But under the tag system, it's just horrible to navigate through these. Not least because the tags on these things are inevitably buggered, and it doesn't seem worth the fuss to try to fix them.
So I'm not all that thrilled with ID3 tag browsing. Unless anyone can suggest a sensible way to get them to behave, I think I'll stick to file browsing in future.
