I haven't until now used itunes, I'd loaded the whole lot from Winamp. Today I downloded itunes and did a complete re-sync, which has solved the "blues" problem, but not the "I - L" one.

Whilst mucking about with it, I realised that Winamp was loading the "comments" box under "composers", re-running in itunes corrected this, as well.

But basically, Oh to have Emplode to do the job!
