Didn't quiet help. Using # along with * didn't help either.

Is it even possible to emit the sound with volume level controlalble by Music settings?

Hello

#define MusicPrefix "#*"
#define MySong1 "my_snd/song1.mp3"

public OnMapStart()
{
    AddFileToDownloadsTable( "sound/" ... MySong1 );
    PrecacheSound( MusicPrefix ... MySong1, true );
}

public Event_PlayerSpawn( Handle:hEvent, const String:szEventName[], bool:bDontBroadcast )
{
    new iClient = GetClientOfUserId( GetEventInt( hEvent, "userid" ) );
    if( 0 < iClient <= MaxClients && IsClientInGame( iClient ) )
        EmitSoundToClient( iClient, MusicPrefix ... MySong1, .channel = SNDCHAN_STATIC );
}

public Event_PlayerDeath( Handle:hEvent, const String:szEventName[], bool:bDontBroadcast )
{
    new iClient = GetClientOfUserId( GetEventInt( hEvent, "userid" ) );
    if( 0 < iClient <= MaxClients && IsClientInGame( iClient ) )
        StopSound( iClient, SNDCHAN_STATIC, MusicPrefix ... MySong1 );
}

If I use the 'play' command, how do I stop the music then?

EDIT:
SDK2013

Have you tried having the sound download to sound/music/ ?

Yes.
I didn't clear sound.cache after each attempt, though.

But according to NMRiH's game_sounds_music.txt, placing it in the music folder is not a requirement:

"NMRiH_Music.Tension_1"
{
	"channel"	"CHAN_AUTO"
	"volume"	"0.8"
	"soundlevel"	"SNDLVL_75dB"
	"pitch"		"PITCH_NORM"
	"rndwave"
	{
		"wave"		"#*dms/tension1/crashed_tension.ogg"
		"wave"		"#*dms/tension1/pressure.ogg"
		"wave"		"#*dms/tension1/quick_uneasy.ogg"
		"wave"		"#*dms/tension1/street_tension_2.ogg"

	}
}

Indeed you can, if you are using sounds manifest.
I believe the tf2 megaman maps implement their music as in game controllable music rather than with ambient generics. Look to that for examples.

http://files.xpenia.org/temp/pic088.png Nope. No manifests. (Pretty sure that /maps/*_level_sounds.txt is autogenerated.)

Could sound generated by EmitAmbientSound be stopped?
If not, well, guess ambient_generic is the last option.
