Not sure if this goes here, lol.
In terms of how it/they sound(s), which language(s) (and/or dialect[s], variant[s], etc.) appeal(s) the most to you? Why is that? :3
My answer is going to sound nonsensical to those of you without knowledge of linguistics; sorry if I don't make sense. I've been into the stuff for so long I no longer have the ability to talk about why I don't like this or that language's sounds without getting into the phonetics/phonology of it, oop.
My first lang is Spanish, specifically the Eastern Cuban variant of the Caribbean Spanish dialect. I like it well enough; it sometimes reminds me of Polynesian languages, the way it flip-flops r/l and avoids codas with s and d. I think it's developing long vowels, or at least the vowels seem longer than usual since it's losing s in some places. So qué es lo que es? ("what's up") sounds like kē lo kē. So yeah, I like it. I do not, however, like Castilian Spanish variants. Their snobbery doesn't help their case, but the god-awful litthhping everywhere sounds like Parseltongue. For some reason th and dh work well enough for English and Icelandic, but in Spanish it just sounds horrible. *sprays with repellant*
Second lang is English. Don't like it. Doesn't sound very nice, and the vowels are fucking all over the place. The native speakers can't agree on how many they've got and the dialects keep switching them, and most of them unstress it and reduce it to schwa. Very nasty stuff. The consonants are nice enough, although I really don't care for the aspirated vs. non-aspirated pot, top, cock vs. spot, stock, scott (I know those aren't real minimal pairs). Oz's English seems to have worked out something for it, tho. It sounds much nicer than the dialects of North America and the motherland. And some of the Scottish or Irish variants are mildly pleasant to the ear, I suppose.
Third lang is French. Hate Québec's laxing of /i/, /y/, /u/, but like their dialects otherwise. At times it's a bit too nasal and crazy, but there's some aspects of it that I really, really, really like, such as the affrication of t,d before the high front vowels. Not that fond of France's dialects, 'cept the Southern ones. IIRC Marseille retains the word-final schwa, which is cool. Overall, however, I love French. Good number of consonants, and there's a bit too many vowels for my taste, but nothing batshit crazy, lol.
These aside, I like Finnish best of all. The sounds roll off the tongue with ease, and the vowel harmony keeps them in check which is nice. I'd like Estonian, but the short vs. long vs. superlong vowel distinction (a =/= aa =/= aaa) is slightly disturbing. Its cousin Hungarian is also nice, but something about it puts me off, I can't quite put my finger on it. I'll figure it out some day. But yes, Finnish is the best. I wish I coulda met Tolkien so I could bro-fist the dude and we can fangirl over it. What's not to love about Finnish? Awesome vowels, good consonants, long vowels AND long consonants, vowel harmony (!!!), and lots of unvoiced unaspirated plosives everywhere.
...There's more where that came from but I'm listening to "Part of your world" (from The Little Mermaid) in Polish (shoutout to Polish speakers: I FUCKING LOVE YOUR LANGUAGE ) and I'm having an orgasm so I'll be back later.
