Songs alright. It's 10xs better at the parts without the electric guitar sample (which rarely sound good in rap songs in general in my opinion). There are plenty of songs I like by Nacho not produced by BSBD so I don't really think he needs them to make dope music but they sure do compliment each others vibe. I feel a big part of it is the layered somewhat spacey & ambient type of production they tend to go for fits really with Nacho's flow and voice.
Also did not know Nacho is almost 33, thought he was in his mid 20s.
