Why does most new music suck?

Cool Frogman, there is only one Led Zeppelin !! I listened to Zep almost exclusively my entire senior year in high school. I actually saw Jimmy Page play in the band The Firm.
So you want something that will get your blood pumping , something more visceral. Try the Raconteurs , album is Broken Boy Soldiers. Jack White is the lead singer in this band. This album is complete and kick ass!!
I also love Consolers of the Lonely !! This one is on Spotify , Broken Boy is not.
Frog are you using Spotify or MOG? It's free with a short 30 second Spotify commercial every five songs. Ten bucks a month for premium service. You can listen to 300,000 albums or so. About 30 million songs. It's just a fantastic way to listen to new music/bands without blowing money on a cd or album.

"there is only one Led Zeppelin"

For sure.

and only one BEatles...

and Dylan...

and The Who...

and Elvis...

and so on....

I used to always be looking for the new "fill in the blank" but eventually learned to avoid that trap and appreciate each act for what they are (or are not). Tough to do sometimes once the bar gets set high!

I happened to be in Kastle, Germany in 70'-71'. In a Hungarian boarding school run by priests and nuns. I was 14 at the time and I first heard 'Whole Lotta Love'. That and Black Sabbath, Deep Purple, Hendrix, and the Beatles were the mainstay there at the time. Oh, and Lee Micheals' one hit wonder, 'Do you know what I mean'. It was fabulous growing up now that I think of it.

I was in Hanau, Germany from 1968 - 1972.
I was young, single, drove a 1970 MB 280SE, Gas was 25 cents a gallon, the autobahns were empty save the military, LPs were $2.50, audio clubs were everywhere and there was live music in the clubs every weekend.

Don't get no better than that!

Cheers

Here's a list from 2011 from the magazine NME. It's their 150 best tracks of the past 15 years. It doesn't matter whether you agree with their selection or not, but it does represent a nice collection of recent pop/rock music. If you are truly interested in finding good recently recorded music it's a good place to start.
