How are loan words viewed? Do businesses work in Maltese? Are monolingual speakers of the language regarded differently than those fluent in English? Do young people in Malta listen to Maltese music?
Businesses do work in Maltese and English. Both are official languages. Its quite rare to encounter a business that deals near exclusively in Maltese. Many prefer Maltese but will fall back to english where necessary.
Regarding monolignual speakers, I think theres a lot of stereotypes for maltese only, english only and code switchers. I think its all a bit silly... So as long as communication can happen I don't fuss.
On Maltese music... There's a lot of low ish quality music then there's a few absolute gems. Look up The Travellers, Lapes, Jon Mallia on YouTube/Spotify.
I was surprised to hear Maltese radio stations played in taxis, while visiting Malta just a few weeks back
