Here's the steps to reproduce:

1) Lookup discID in Piccard. When no matches are found, click "Lookup Manually"
2) Search for artist, in my case, "the smokin' mojo filters"
3) Select the 1 result and click "Add a new release"
4) Fill title as "Come Together", then hit "next"
5) Select "Do not use any of the above releases as a starting point", hit "Next"
6) Now try and add the track listing (from here http://www.discogs.com/Smokin-Mojo-Filters-Come-Together/release/920609)

At this point I find some weirdness if I switch to the advanced editor, and on submission of the page I always get:

"A track name is required on track 1.
A track name is required on track 2.
A track name is required on track 3.
A track name is required on track 4.
A tracklist is required"

The page also throws away what I've entered, and I can't get it to accept the track listing.

I wonder if the single quote in the artist name is causing a problem somewhere?
