Ygtjki

The English translation of a hymn by Prahlada in Srimad -Bhagavatam (7/9/40) reads as

My dear Lord, O infallible one, my position is like that of a person who has many wives, all trying to attract him in their own way. For example, the tongue is attracted to palatable dishes, the genitals to sex with an attractive woman, and the sense of touch to contact with soft things. The belly, although filled, still wants to eat more, and the ear, not attempting to hear about You, is generally attracted to cinema songs. The sense of smell is attracted to yet another side, the restless eyes are attracted to scenes of sense gratification, and the active senses are attracted elsewhere. In this way I am certainly embarrassed.

Did cinema-songs exist at the time of Hiranykasipu and Prahlada? Any evidence other parts of Bhagavatam or any scripture?

The verse is not talking about cinema songs. Here is the original Sanskrit:

jihvaikato ’cyuta vikarṣati māvitṛptā śiśno ’nyatas tvag-udaraṁ śravaṇaṁ kutaścit |

ghrāṇo ’nyataś capala-dṛk kva ca karma-śaktir bahvyaḥ sapatnya iva geha-patiṁ lunanti ||

Prahlada is talking about how the different sense-organs are pulling him in different directions, towards different kinds of sensory pleasures. And one of the sense-organs he mentions is the Shravana or ear. Srila Prabhupada is just supplying cinema music as an example of the sort of sensory pleasure that the ear pulls people towards. Neither cinema, nor music of any other kind, is mentioned by Prahlada, but presumably music is the sort of thing that the ear is pulling him towards.

According to the English translation of the Srimad-Bhagavatam by Gita Press Gorakhpur, Srimad-Bhagavatam 7.9.40 translates as follows:

Not fully gratified, the palate pulls me, O immortal Lord, in one direction (towards dainties); the generative organ drags me in another direction (towards sexual gratification); the tactile sense, the (empty) stomach and sense of hearing pull me in other directions (viz. towards objects that are pleasant to touch, substantial food and the melodious sound or voice respectively); the olfactory sense drags me in a quite different direction (towards sweet-smelling flowers, scents and so on); while the eyes, which are (very) restless, and the faculties (organs) of action pull me in yet another direction (viz. towards things of beauty and objects to be attained through the various organs of action). (All) these tear me (even) as a number of co-wives wrench a householder (each to her bedroom).

NO.

The 'Cinema-Song' is just an unwanted addition by the translator.

The original sloka is:

jihvaikato ’cyuta vikarṣati māvitṛptā
śiśno ’nyatas tvag-udaraṁ śravaṇaṁ kutaścit
ghrāṇo ’nyataś capala-dṛk kva ca karma-śaktir
bahvyaḥ sapatnya iva geha-patiṁ lunanti

So here only ears are referred to [which are attracted to sensual music]. Cinema-Song is just unimaginable as there was no cinema at that time when our scriptures were compiled.

Here's an alternate translation (G. P. Bhatt & J. L. Shastri) of that verse where there is no mention of cinema songs or any type of songs for that matter:

40. Oh Acyuta! My ungratified palate drags me in one direction and sexual desire (lit. the genital organ) pulls me to a different direction, while the senses of touch, hearing and the abdomen gravitate me to some other direction. My olfactory sense, the constantly moving eye and faculties of action draw me in different directions — all these pull (in different directions) like a number of co-wives dragging their lord of the house (to their bed-rooms).

As to why Prabhupāda chose those particular words in his translation, the likely reason is, he wants his disciples to stay away from anything that has to do with the movies. According to him, the only songs his followers should sing and listen to are a few songs about Kṛṣṇa approved by ISKCON:

In our Kṛṣṇa consciousness movement we do not allow any song that has not been approved or sung by bona fide devotees. We cannot allow cinema songs to be sung in the temple. We generally sing two songs. One is śrī-kṛṣṇa-caitanya prabhu nityānanda śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda. This is bona fide. It is always mentioned in the Caitanya-caritāmṛta, and it is accepted by the ācāryas. The other, of course, is the mahā-mantra — Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. We may also sing the songs of Narottama dāsa Ṭhākura, Bhaktivinoda Ṭhākura and Locana dāsa Ṭhākura, but these two songs — "śrī-kṛṣṇa-caitanya" and the Hare Kṛṣṇa mahā-mantra — are sufficient to please the Supreme Personality of Godhead, although we cannot see Him.

His dislike towards movie songs is also evident from his commentary on another verse:

But here we find that millions and millions of years ago, when Nārada Muni was a Gandharva, he neglected the order to glorify the Lord, and being mad in the association of women, he began to chant otherwise. Thus he was cursed to become a śūdra. His first offense was that he went to join the saṅkīrtana party in the company of lusty women, and another offense was that he considered ordinary songs, like cinema songs and other such songs, to be equal to saṅkīrtana. For this offense he was punished with becoming a śūdra.

Spiritual sensations are vague and weak compared to more dominant and powerful sensations of body.. the eye, ear, touch hence they mislead. This is Prahlada's basic lamentation in his helplessness. And it is a fact of human existence of all time..

Adi Shankara's Nirvana Shatakam recognizes the central Spirit in himself, forming the essence of Advaitha in his more advanced view. He asks not to go astray pulled by powerful compelling senses for gratification of taste, external beauty or sensuality but to stay on with the Spirit that can eternally sustain anyone in a continuous state of Ananda, that was earlier felt as pure Bhakthi in Prahlada's case.

As a personal note I may be permitted to add from Goethe's Faust ... such sidetracking tendencies on Mephistopheles were referred collectively to as the Devil.
