Beer, I get what you are saying now. I am familiar enough with digital audio and my home studio to record, but only (very) basic demos of song ideas, wich is why I have challenges with fluctuating volume levels recording myself(though not with my pitch, Iam very anti-melodyne or whatever the latest 'cheat' for lazy singing is) and believe if ya cant sing it, move over and make room for someone who can). My husband takes over from there as far as the techie stuff. I just dont 'do' the auto sliding faders, more complicated midi, etc. (Hence the simple nick 'SingyThingy' and not 'Audio Mastermind Engineering Genuis Thingy').
Anyway, I totally get how the use of 'shouty' singers /simple backings is cheap and easy to produce...kinda like a lot of backings used for certain popular styles can be replicated easily just messing around with simple comp based programs, right? (not that I personally can do much that route, but have heard plenty of such 'music' coming from moniter speakers duing off time , if you know what I mean

)
Lol, I might just buy the track produced by a drill and spoons banging a Ford Fiesta, depending on the mix and overall sound, but I do see your point.
I would love to be able to agree completely with you as far as 'real 'singers also being songwriters, because I am as much a songwriter as I am a singer, and admit I do think less of artists , for the most part, who get co-credits for adding a few words into the lyrics and such.....but some exceptionally gifted vocalists are great when it comes to INTERPRETING songs, and they have my respect. Ella Fitzgerald, for instance...and Katharine Jenkins , who you like and I agree is gifted, doesn't write , unless I am mistaken, which I could be.
On to the culture/media aspect....yeah, sadly sex/image sells. This has got me thinking ...about image, and media hype, wich fascinates me and is the main reason I watch shows like xfactor/A idol. I think maybe culture dictated music trends in decades past, but not so much now. There was a bigger difference in trends in various countries, from the research Ive done, pre-cable tv, pre-internet, and pre easy-access to flights for musicians, etc...and so on. So maybe these 'reality shows' and trends in image/music are just the natural progression of the global hype-machine (paired with the easy/cheap music mill capeabilities you mentioned) to create this 'fast food' music thing that has kind of taken over in the last decade or so?
AS far as saying a song belongs to a singer who is signed, let's face it, what major would even allow much of that? The profits are in the publishing, and the artists tend to get !@#%^ed over. I have seen enough to steer very clear , at least for now. Only desperation and years of failure would ever tempt me to go crawling to a major or reality show, and as far as the reality show angle, any artist who has definite ideas of what they want to do probably prays to make the top 12 and then 'lose'.
I think the difference between us is that I give 'shouty' singers(who dont lose their tone and have at least some agility/dynamics) the benefit of the doubt. I assume they can also sing a proper melody and have some versatility. Through experience, I can usually tell when someone is only a shouter.
Based on your posts, I am guessing you have had to hear your share of shouters? I can understand where someone who is a sound engineer or such would develope an allergy over time, haha.
Anyway, I watch xfactor to study the hype machine and for the ocasional brilliant(IMO) performance. I hate the 'sob stories' and have some rather unpopular opinions about some of them. It is interesting to watch how most people eat what the media serves up, either getting into the panto side of it, or feeling clever for 'seeing through' what looks like carefully orchestrated 'mistakes' that show the 'manipulation....if that makes sense?
