Another slander.
These are two Fatwas of Ayatollah Seyyed Ali Khamenei about music.
Q: What are lahwī music and singing?
A: Any music or singing which due to its characteristics keeps human beings away from Allah, the sublime, and away from moral merits and spiritual matters and drives them towards sinful acts and carelessness is lahwī and ḥarām(forbidden).

In shia fiqh( jurisprudence), just lahwī Music or ghinā’ are haram, not all music.
Again this discussion is about Hadith and not about Fiqh . Nevertheless there are plenty Shia Ahadith prohibited Music :
01.Hazrat Imam Ali ar-Reza (a.s.) remarks,
"A person invites Divine wrath when in his house instruments like flute, drum and chess are played for forty days. If this man dies within these forty days, his death would be of a sinner and a transgressor. His place shall be in Hell. And what a dreadful place it is!"
(Mustanad al Taraqi)
02.The Holy Prophet (s.a.w.s.) has stated,
"A person who possesses a sitar, on the day of Qiyamat will be raised with a black face. His hands will be holding a sitar of fire. Seventy thousand angels with maces of fire will be hitting him on the face and the head. The singer will arise from his grave, blind, deaf and dumb. The adulterer will be similarly raised. The player of flute will also be made to rise in this way as will be the drum player."
(Mustadrakul Wasael)
03.Hazrat Imam Ali ar-Reza (a.s.) has said,
"To listen to a musical instrument is one of the Greater Sins."
(Mustadrakul Wasael)
04.Amirul Momineen Ali (a.s.) says,
"Angels do not even enter a house that has wine, drum, tambourine or a flute. Even the prayers of the inhabitants of this house are unacceptable. They are deprived of barakat."
(Wasaelush Shia)
05.The Holy Prophet (s.a.w.s.) has also said,
"The Almighty Allah has sent me as a mercy to the worlds, to guide the people. And He ordered me to eradicate the playing of flute and other instruments of music, all games of vice, idol (worship) and all practices of the days of ignorance."
(Mustadrakul Wasael, Chapter 79)
06.Imam Ja'far as-Sadiq (a.s.) reports from the Holy Prophet (s.a.w.s.) that he said:
"I prohibit for you dancing and playing flute, drums and tabla."
(Al Kafi)
07.Imam Ja'far as-Sadiq (a.s.) has also said,
“Even learning to sing or play music and teaching it, to sing and play music, to be paid for these things or to be in any way engrossed in these vices is Haraam."
(Tohafful Uqool)
08.The sixth Holy Imam, Imam Ja'far as-Sadiq (a.s.) said,
"Listening to music, songs and useless words cultivate hypocrisy in the heart, in the same way as algae grows in water."
(Al Kafi)
09.Al Kafi mentions a tradition of Imam as-Sadiq (a.s.) that,
"Singing and music is a nest for the bird called hypocrisy."
10.Imam Ja'far as-Sadiq (a.s.) says:
"The house where music is played is not safe from sudden disasters. Supplications at such a place are not answered. Angels do not enter this place."
The Holy Prophet (s.a.w.s.) is quoted to have said:
"Molten lead shall be poured into the ears of one who listens to songs, intently."
(Mustadrakul Wasael)
11.It is also narrated from Imam Ja'far as-Sadiq (a.s.) that he said,
"Whenever a person begins singing, two satans mount on his shoulders and continue to hit their heels upon his chest, till the time he sings the song."
12.Hazrat Imam Ali Ibn Musa ar-Reza (a.s.) said,
"One who avoids songs shall be provided by Allah, a tree, which will produce such a melodious sound as has never been heard by anyone. But the one who has not kept himself aloof from songs will not be able to hear this sound."
(Al Kafi)
13.The following tradition of Allah's Messenger (s.a.w.s.) is recorded in the book Tafseer Majmaul Bayan,
"One who has listened to too many songs will not be able to hear the Ruhaanis on the Day of Qiyamat."
"Who are the Ruhaanis, O Prophet of Allah (s.a.w.s.)?" someone asked.
The Prophet (s.a.w.s.) replied,
"They are the melodious singers of Heaven."
A similar tradition from Hazrat Ali (a.s.) is found in Nahjul Balagha,
"Hazrat Dawood (a.s.) will be the chief of the singers of Paradise."
(Nahjul Balagha)
14."The people will listen to such melodious songs from Hazrat Dawood (a.s.) in Heaven, the like of which have never been heard by anyone. However only those who have refrained from listening to songs in this world would be able to hear them."
The Holy Prophet (s.a.w.s.) said:
"Singing is the stepping stone to fornication."
(Mustadrakul Wasael)
15.Imam Ja'far as-Sadiq (a.s.) says,
"And all those wasteful pastimes are haraam which make one forgetful of Allah; like songs and playing musical instruments."
The traditions concerning the signs of the last stage before the Zuhoor of our Imam (a.s.) mention music:
"And you shall see that music will be so prevalent that no one will dissuade others nor will he find in himself the need to do so. And you shall see that music would be openly played even in the two sanctuaries (the city of Makkah and Madinah)."
(Mustanade Naraqi)
