Why even use 'good and bad'? It's 'I like it or I don't like it' Sadly, that requires exposing yourself to everything, which is time consuming. SO, Perhaps it'd be nice if someone (i.e. me) actually tried answering the question instead of saying 'the answer sucks' ya freakin' hippies.
If you like a wide variety of music, and at the same time, a lot of that music happens to be in a similar style, you may want to know 'wow, there must be a name for this style, since it's so prevalent.' and lo and behold, there is!
Take, for example 'techno' which is one of the most widely misused genre names in existence. techno describes a certain kind of electronic music that generally features cheesey fake clap sounds on every other beat, 4/4 timing, and obligatory synthy sounds and voice recordings...similar to Strongbad's description. This genre hardly exists anymore except in immitators who emulate the style that was more popular in the early 90s.
While that description is pretty broad, it's easier to compare when contrasted with the OTHER genres that it is mistaken for. i.e. Trance, goa, eurodance, downtempo, breakbeat, IDM and such. Even those subgenres have subgenres.
Then you have metal, industrial metal, thrash metal, screamcore...dark metal...etc etc.
Rock, alt-rock, post-rock, grunge, indie-rock, space-rock....blah blah blah
Acid jazz, jazz, abstract jazz, blues, RnB, swing, Big Band
Rap, Hip Hop
and of course classical music is divided more by time period than style, like Baroque and such.
those are a few examples of genres and subgenres. look them all up, maybe you'll find something you like.
