I’m in a similar boat, Spanish degree from college, but learning Portuguese now, and I’ve found that kids programming like Sesasme Street (Rua Sésamo) is really great for getting some fundamentals. They tend to speak slower, avoid idioms and focus on foundational parts of the language. And the good thing is, you can find all 30ish episodes of Rua Sésamo on YouTube

I would not recommend using music to learn a language, especially if the lyrics don’t stick in yr head easily (which IMO is basically its only advantage). The lyrics normally do not contain everyday vocabulary and/or grammar, it’s just not useful for communication. It is, however, often helpful for forming some sort of “emotional bond” with the target language, increasing motivation to dig deeper into it. It can also give you a better access to its specific, well, musical qualities. But then, just the bare spoken (not sung) sound of it can accomplish that just as well, if you’re willing to listen. Music will not help you get along with everyday tasks, improving communications, talking about yourself and other subjects, participating in discussions etc. Intentfully listening to spoken text/conversations is far more effective for that - even more so if it’s authentic (not scripted, not produced for recordings, read by actors etc)

Keep learning Portuguese and you’ll figure it out someday

Nope, not even gonna try.

One thing being worse doesnt make the other better, I know for example that french counting is basically insanity. But then again, when you get really deep into portuguese things get real non sensical

Do not worry too much. At least in Brazil, almost no one uses mesóclise on casual conversation, and it can come across as pedantic.
