The New Wave of Music Reminds Me of the Old

I'm not sure if listening to music for so many years has given me a very broad music reference library in my head. Why do 4 out of 5 songs I hear on Record of the Day sound exactly like something that could have been recorded more than 20 years ago? Is it a younger group of musicians discovering music I grew up with and having it seep into their subconscious psyche?
Here are a few examples. These references came to mind within a few seconds of hearing the song:

Maybe I'm Crazy is a demo by two musicians called Mike. This could be a Nick Gilder song. He recorded Hot Child In The City. Surprised no one had a hit with that again. There was something pleasantly pop and sleazy going on in that song.

Avenue is a pop band out of the UK. They are being touted as the next boy band. Their song Last Goodbye is Rick Springfield without the 80's production and keyboards. It's actually a good song if you don't watch the video, which drags the track down. Rick Springfield had tons of energy in his live show. From the video I've seen, they do not share that same energy. The track is full of it, but the lads aren't translating that. They do pogo though.

VV Brown another Brit, wants to be the modern Ruth Brown. You can hear the influence in Crying Blood. The R&B/pop revival coming from the UK, initiated by Amy Winehouse is in full swing. This is one from left field, but even with the remixes, this song reminds me of Freddy Cannon: He of Palisades Park and Action fame. View his performance of Action on YouTube. Avenue must have been studying his moves. Action was the theme song to Where the Action Is, penned by Boyce and Hart. The show's hosts were Paul Revere and the Raiders and it took musicians to a different location each week. It's not that Crying Blood specifically sounds like one of Freddy's songs, it reminds me of all of his songs.

Both Avenue and VV are on Island Records.
