How to alternate two 4Gs in a playlist?

[apollolux]

What feels best for you at the moment for your day-to-day life?

My first instinct was to run BIABWS 8 hours straight, followed by DAOS straight. As for time-of-day, with that setup it would most likely mean from late morning/when I get up through late afternoon/early evening for the first half, and evening to early part of sleep for the second half, since starting the playlist later in the day may not guarantee I would successfully listen to the second half during sleep, given the chance of my earpods slipping out of my ears due to night movement.

Whatever order I choose here, its success would likely be replicated at a later date running BASE 4G and MLS/US 4G in tandem as well after I graduate.
