Just personal observation, maybe it feels different for a professional English song lyric composer.
I don’t have a spreadsheet, but so many characters have the same ending sounds in Mandarin that I could easily find a rhyming word when writing song lyrics.
English is a struggle to find a rhyming word that fits into the context of the contents, and it feels kinda like a forced rhyme.
I haven’t really spoken Mandarin for over 15 years, somehow it’s still easier to do rhyming.
P.S. Cantonese has more variety of sounds and less characters have the same ending sounds, so its harder to rhyme in Cantonese.
Japanese, not restricted in the same way as Chinese tonally, and having a long tradition of both song and poetic lyrics, lends itself extremely well to hip hop/rap. This is not to say it’s better than Chinese for this - only different. There are so many excellent Japanese hip hop artists.
