soliek, you’re right, but it goes both ways. With the ever-increasing ease of putting out music, unknown artists, that HAVE talent, can get noticed more easily, when they couldn’t have in earlier decades. So while there may be more “garbage” (for lack of a better word), there’s the same amount of undiscovered musical talent. You just have to look for it.
Also, in my opinion, being a famous musical artist/ singer does NOT necessarily mean you are a great and talented artist/singer. Look at the pop music industry right now. The vast majority of them, IMO, have very little talent, and are only famous for other reasons, whereas most classical/jazz artists are unknown, yet possess an incredible amount of talent.
