I used Calibre 6.0 too. Dad's Kindle does work with the mobi so I guess it is all there although I've struggled with anything else I've tried...

If you start a conversion manually, Calibre does offer a range of input and output profiles so it's possible the program picks the right profiles for the Kindle device it. It's also possible that mobi needs a different graphic format to svg. I don't know.

One thing I could easily try is to see what happens with png graphics.

The SQLite database contains more that it needs at the moment. I'm not sure there's any point in having the SW there at all. I could make it downloadable but it's an obsolete proprietary format. Keywords aren't used but I'm unsure whether I'd want them or not if I did have another play with the app.

In the thread I quoted Joe on about release versions, Susan of DT says:

There are 10,000 songs in the Feb07 edition, vs. 9,000 in the 2002 edition, roughly.<\blockquote>So I think your song counts are about right.
