I show 'hit the lights' as 4:18 and 'motorbreath' as 3:08 which total to 7:24. 'one' is 7:25, so no problems there
'no remorse' is 6:26 and 'unforgiven' as 7:27, so again no issues
you can go longer to shorter, you just have [dead] space at the end, and 1 second won't even be noticeable
with 'moth into flame', you're going to have to truncate it or by working some magic in audacity, cut out a section (or sections) of the song equating to a total of 25 seconds so that it's still seamless but has a running time of of sad but true's 5:25
* times given are from my actual cd rips. the times in the game rom may be slightly different and match what you've listed (I don't have pinball browser with me or the metallica rom to check right now)
