I know what my problem is with the music Gus likes.
Even though I do think in english sometimes I still hardly listen to more than 30% of the lyric content in tunes if the language is any other than my native.
Might be something related to how my attention works.
Before I started speaking english more, I was already switched to the mode of listening that strains to discern the elements that make the whole, to catch the way the timbres morph etc.
Hence I will never be able to get into pop music properly. Except it's polish pop. For better or worse.
