Going through Audiotree Live series https://musicbrainz.org/series/1e98c3c0-60c7-4342-86f8-f75e18666a74, I found some release titles that differ from what seems (or in the past) to be the naming standard.
Majority use(snail mail just as example):
Audiotree Live - Snail Mail
More recent ones and some outliers use:
Snail Mail on Audiotree Live - Snail Mail
Which is the correct format? I want to say the former would be correct.
