The songs will be separated by a lot of variables once the actual song selection fields are revealed. The venues the songs are included in seems to be extraneous information to include in the soundtrack list, tantamount to listing the scene each song appears in for the soundtrack to a movie. Fields like the original release dates of the songs and the first albums they appear on will be infinitely more informative (and relevant). Including sortable fields for things like venues and difficulty seems a dubious practice at best and a trivial one at worst. Not every bit of information that's included in a press release needs to be reflected in the article.
