For me, music plays quite an important part of my life. I like to listen to a lot of under-rated bands which most of you have probably never heard of but I believe have great talent. The music of today is sometimes quite good (mostly, it's just a catchy beat) but the themes are usually pretty meh. I think why the music is popular today is that the radio plays it a lot and then a lot of people think that it's good but mostly it's just because other people will know the songs and they won't be laughed at for listening to it. All the songs usually have, where I live near London, is catchy tunes, there is some talent to be fair but not a lot.
Sorry for the semi-wall of text but I'm just curious on other people's opinions.
I don't think it's necessarily fair to automatically compare two different genre's of music and whatnot. It's a little like comapring da Vinci to Pollack: the two lived in very different times and crafted artwork surrounding different themes using different styles and methods.
The same can be said of today's music. The Beatles and Kesha are considered to be pop musicians, but they obviously have very different ideas of pop, not to mention they each had their own experiences and different equipment and technology to shape their sound. Music is all subjective.
Today's music, I think, some of it is not necessarily music. The majority of rap songs are really just words with no melody placed over an automated drum machine. Some make use of synthesizers. But again, not all music is the same and can be compared like it is. For some people, it's about melody. For some, it's rhythm. For others, it's lyrical themes. Everyone finds "music" in different things. Like I said, it's all subjective.
My subjective viewpoint, recent music has really focused on hooks and making use of synthesized instruments. This isn't necessarily a bad thing. Some songs nowadays are good all around (yeah, even some of those dance-pop tunes Katy Perry gives birth to every month) with the lyrics, instrumentation, and melodic structure. Others, well, are a hit and miss. I also like older songs too. I'd say my favorite song is Boston's "More than a Feeling." I like these different songs because they say different things to me. I don't like music that I don't relate to, nor do I like music that isn't relatable at all.
Music is music to different people with different tastes. Just because someone drenches their voice in Auto-Tune doesn't mean they haven't crafted a good song.
Sorry for the whole freaking essay, but I just get annoyed when people write off modern music just because they don't have a guitar in them or because the singer can't hit every note perfectly.
