They very clearly showed how you got a ton of leeway in how to pool, rotate or cram your songs to fit optimizing the support mechanics without losing out on damage. Could it still end up being problematic? Sure.

But right now song-play is utterly strict. The timing has to fit. The new ones have a lot of leeway, which is a marked improvement, and in fact is what first enables utilizing them for secondary effects (the current +damage buffs have no such contingency) in the first place.
