These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

This is because Taiji gained most of his fame from his first major band, which he'd stayed with longer.
Taiji had showed up at every memorial show for Munetaka, and his song "Black Widow" is still sometimes performed live by the band (now as a tribute to him as well). It is also most likely that his personal problems were why he left the band, as this was around the time his life made its turn for the worse.
Harsher in Hindsight: Pandemonium, especially the song "Bloody Doom," but pretty much the entire album. Released in November 2001, and reading like a rant about the entire decade to follow 2001 and the War On Terror.
Ho Yay: Loudness doesn't tend to indulge that much in fanservice or onstage/interview admissions or the like (nowhere near as much as, say, X Japan or Buck-Tick) but it's had its moments.
The 1991-1993 era featured onstage fanservice - usually between Masaki and Taiji, though both would occasionally share the love with the others.
There were some rumors that The Mentor friendship between Munetaka and Taiji could have had this dimension to it.
In a lyrical example, the song I Wonder, is Minoru singing to the now-dead Munetaka about his love for him and how much he misses him.
