Look, I'm not some snob who only goes to select operas, provided that the lead can sustain something above E-flat. Frankly, I prefer music without vocals most of the time, or sang in a language I don't understand, so that it can be in the background without distraction. My other on-and-off interest are 'misheard lyrics' and the like.

Send/post your stuff, please. Even if I won't like it, it's your fun and maybe I can help with The Algorithm :D.

btw am I wrong or is the most common answer from Polish peeps upon finding out a non-native/foreigner is trying to learn Polish: "...why?"?

Why would you want to learn a language that's only spoken by 38-ish million people who all live in a country where anyone halfway educated has some B1-level of competency in English? It's like learning Russian, if Russian was less influential on surrounding/related languages and had even more exception-driven grammar. It's a good starting point, 'cause I can kinda get at least the gist of all Slavic languages from Russian to Croatian, but that's after 20-some years of exposure.

Don't get me wrong, we have some dope literature, but the level of effort required to approach appreciation exceeds learning Archaic Greek to read the Iliad and Odyssey (and little else if anything, Archaic ain't the same beast as Attic/Ancient/Classical) or whichever sub-Saxon variant of Old English to read Beowulf (ditto). And, frankly, unless you plan to move to Poland, about as useful as either of those.

It's universally appreciated when tourists/workers learn some Polish, sure. Even little phrases go a long way. But, in general, we're understanding of difficulties and sheer phonetic complexity. The only time I felt anything resembling contempt to someone not bothering was with a Turkish co-worker who, after living here for 5 fucking years, couldn't even do groceries without relying on his pitiful grasp of English.
