That's a very interesting list that
@RobMCFC .
I think - sadly - the generation who invented rock'n'roll are just dying out. The people who were in their teens in the 1950s are too. Essentially, that era of music is not being remembered and not being listened to as much.
However, anyone who likes rock and pop music is in debt to these legends. The likes of Chuck Berry, Little Richard, Buddy Holly, Ray Charles, Muddy Waters and Jerry Lee Lewis massively influenced those who came next - The Beatles, The Rolling Stones, Small Faces, Kinks, The Who etc. I remember hearing Little Richard talk about doing a tour and these young kids were in awe of him and kept wanting to talk to him and he wasn't too bothered about it. They kind of got on his nerves a bit as groupies...it was The Beatles and McCartney was a massive fan. You only have to watch "Get Back" to see how Lennon and McCartney loved playing the songs they grew up with - made in the 1950s.
I am a big fan of the 50s rock n rollers. Just listen to the energy that blasts from Little Richard doing Good Golly Miss Molly for example. It's like punk rock on a piano! I like "The Big O" and what a singer he was, but I'm not surprised he didn't make it. The other rock'n'rollers all contributed enormously to modern music and there's plenty of superb music they made.
I've said it before, but essentially The Beatles changed music in a few short years. Music before them sounds maybe too simple, with not too much to it. Nice words, nice melodies but nothing much more than that. It was definitely music for teenagers and wasn't expected to last the test of time. Maybe this chart proves that! :)
However, The Beatles moved it on so quickly that the music of the 50s - and especially 40s - just sounds really old fashioned. Music after The Beatles is much more complicated and 'modern'. Good Molly Miss Molly was released in 1956 and 10 years later "Revolver" is released and a year later Sgt Pepper. I think shows how much they moved music on. Imagine hearing Strawberry Fields as a teenager - you're not going to bother with Roy Orbison are you?
I'm not surprised Madonna isn't on it, she's done some nice pop songs but is over stated as a musician in my opinion. The Beastie Boys are good, but honestly I'd be surprised if anyone would have them in their top 15 artists.
Anyway, the Top 100 and "Not the Top 100" make fascinating lists!
