Background Music System: How do i do this? [SOLVED]

Newbie & Debugging Questions
#1

So i have a ton of tracks for my game already (all on my youtube channel)

but the sound system i have right now is hella buggy and doesnt passively play tracks like i need it to.

I need a system that plays a track, then when its done pick an amount of time based on a range to wait before playing the next track, then pick a track randomly from a list of tracks that can play depending on circumstances (time of day/area of map etc)

In short, a passive version (like minecraft) of terraria’s music system.

Can anyone give me any pointers?

EDIT: Tinysound turned out to be perfect and the sound system is now fully functional.

void tick() 
	{
		if (TritonForge.Screen != "Title" && Menu.playing() == true)
		{
			Menu.stop();
		}
		if (TritonForge.Screen == "Game")
		{
			if (music == false)
			{
				GoodMorning.stop();
				May.stop();
				timer--;
				if (timer  <= 0)
				{
					int i = new Random().nextInt(range) + 1800;
					timer = i;
					if (Sky.time == Sky.day)
					{
						int m = new Random().nextInt(5);
						if (m == 0){GoodMorning.play(true,musicvol); GoodMorning.setLoop(false);music = true;}
						if (m == 1){May.play(true,musicvol); May.setLoop(false);music = true;}
						if (m == 2){Sunset.play(true,musicvol); Sunset.setLoop(false);music = true;}
						if (m == 3){Winter.play(true,musicvol); Winter.setLoop(false);music = true;}
						if (m == 4){Calm.play(true,musicvol); Calm.setLoop(false);music = true;}
					}
					if (Sky.time == Sky.night)
					{
						int m = new Random().nextInt(2);
						if (m == 0){Sunset.play(true,musicvol); Sunset.setLoop(false);music = true;}
						if (m == 1){Dusk.play(true,musicvol); Dusk.setLoop(false);music = true;}
					}
				}
			}
		}
		System.out.println(timer);
		if (GoodMorning.playing() == false &&
			May.playing() == false &&
			Sunset.playing() == false &&
			Winter.playing() == false &&
			Calm.playing() == false)
		{
			music = false;
		}
