Might I suggest a little Frankie Valli & the Four Seasons for your collection?
Many of the songs on this album
are classic, even if you don't recognize them all by name.
(I gotta admit it's something of a 'guilty pleasure' for me. I used to listen to these guys constantly on my 8-track as I was cruisin' in my '69 Malibu... and... oh yeah the soundtrack to American Graffiti
... Simpler times, to be sure)
