Multiple tags delimiter (e.g. Genre or Artist) syntax

[rweten]

I thought I'd append a new question to this thread as it is related though perhaps more basic.

Like others I've been a user of Twonky in the past and my file tagging has reflected what Twonky would accept. So, for instance, I've been able to get away with using commas to separate multiple items in a particular category such as Genre, or Artist. So, if I put 'R&B,Soul,Pop' under Genre it will then show up accordingly under each of those genre classifications in the browsing tree (in Twonky).

It looks as though I need to change that rather casual usage of commas to use the formal \\ delimiter described elsewhere in this thread. However I have a couple of queries:

1. I'm not quite clear on whether simply shoving a \\ into my Genre field actually achieves two separate Genre entries for that file. If it does, great; if not, then how do I achieve it? I am using MP3TAG, by the way.

2. I am not looking forward to manually going through my database and changing commas for \\. Can anyone describe to me simply how I could automatically do that in MP3TAG? I'm generally a quick learner at these things but I am not experienced at using things like scripts. A muppet's guide to how to automatically re-tag would be just incredibly helpful.

3. Finally, and just to complicate things a bit, I have been a bit inconsistent about my use of commas as a delimiter. In some places just a comma separates two categories; in other places there is a blank after the comma. Guidance on how to select either ',' or ', ' to be replaced with \\ again very helpful.

Thanks,
Richard
