“Under the Bridge” is also a sumptuously mellow anthem about, well, drawing some blood under a bridge, and let just say that as a doofus 12-year-old who still didn’t know enough to even want to try any drugs, I was in no position to wrap my head around the heroin of it all, and that goes for every ’90s rock band I adored that occasionally or not-so-occasionally wrote hit songs about heroin, which was most of them.
