maybe i'll try and pair them together in a later test run. there'd be no stat revisions or anything. so yeah, it's a pretty easy thing to plug-and-try. update 2/24 i managed to get almost 3 era's worth of songs into the Build folder. all went well until i would get to track #39. it played...and played...and played in a continuous loop, track 39 (Lullaby by George Gershwin). i was finally able to pinpoint this after running a few trials. so, with that said, i won't have any type of cap on songs...why should i? i can merge tracks together and chop away at the overall track count. this lead me to merge a bunch together, based off of the year each track was written. this makes it real easy to line up in the folder and also the text file.this also means that there will be a track for each year (1895 through 1924) of the scenario (at minimum). some years have multiple tracks merged onto one mp3 file. there are a bunch that have only one track per year. i've gotten up to 1918 on the 'merging' of files. of course, it's not easy picking the right tracks...listening through many, many songs before deciding. i've even branched slightly outside of the Tin Pan Alley genre, although still well within the so-called "Popular Music" of the day. tinkering with the sound settings lets me do a little more. and in-game, they sound really nice, better than v4.0, more ambient which is exactly what i'm aiming for.
