How can I fix my sound system to to work in-game?

I made a sound system that plays songs selectable from a list. It worked fine in Studio but does not work in-game. The sounds do not copy to my Parts that are speakers, most of the time. But when they do the song does not play. Is there any way to fix this? I'm thinking Remote Events as a fix but I'd like to know other options. All help is appreciated.

P.S I know there are unused variables, had to shorten the script.

Songs = game:GetService("ReplicatedFirst").Storage
SoundTable = {Songs["0To100"], Songs.Antidote, Songs.BecauseI, Songs.BlackBeatles, Songs.Centuries, Songs.ColdWater
	, Songs.Colt45, Songs.DatBeat, Songs.DontMind, Songs.Froze, Songs.Heathens, Songs.Meek, Songs.MyHouse
	, Songs.OneDance, Songs.Panda, Songs.Panda, Songs.PurpleLambo, Songs.RICO, Songs.Ritual, Songs.SevenNationArmy
	, Songs.StartedFromTheBottom, Songs.StressedOut, Songs.TakeMeToChurch, Songs.TheNights, Songs.TheQuan, Songs.Ultimate
	, Songs.UpLikeTrump, Songs.UsedToThis, Songs.WhereYaAt, Songs.WorstBehaviour
}
