Is reflecting upon a choir conducive to the path of Enlightenment?

A few years ago, I read in the introduction of a Spirituality book about this story of Gautam Buddha. I've forgotten the name of the book, but this poetry has stuck in my memory for ever. The story goes something like this: *The young prince Siddhartha is sitting in the garden, having felt disgusted by the vanity of the celebrations going on in the palace. That's when he hears a group of celestial beings passing by singing melodious choirs:* > *We Know not whence we come,* > *nor where we float away* > *Time and again, we tread this round, of smiles and tears* > *In vain we pine to know* > *whither our pathway leads* > *And why we play this empty play* Each time I remember or reflect upon this choir, I get a profound feeling of anicca. I know that even thinking about this is also a sign of attachment, as even those thoughts are impermanent. But is it wrong to get energized or inspired by a choir, even if the inspiration is towards the path of enlightenment? As a side note, has such an anecdote really happened with Gautam Buddha? Is there such a mention in any suttas?
