Whats on your turntable tonight?

Gordon Lightfoot, Sundown, MFSL HSM
Mannhiem Steamroller, Fresh Aire III
Amanda Mcbroom, West of Oz and Growing Up...  Sheffield Lab #13
McCartney, RAM 180g new release
Confederation, Sheffield Lab#9 (pretty good banjo)

I file my LPs alphabetically and play them in that order.  Tonight is:
Bach- Fantasia and Fugue in C minor EMI MFSL HSM
Joan Baez- Diamonds and Rust,  Nautilus SD HSM
Boston- Boston, Epic CBS HSM
Lindsey Buckingham, Christine McVie 180g 2017 release (excellent)
Judy Collins- Judith, Electra SD HSM
Rita Coolidge- Anytime...Anywhere, Nautilus SD HSM

Can someone explain to me the advantage of 45 RPM?  How can moving the groove past the stylus faster giving the stylus less time to track the groove result in better sound?  I don't get it.
