Rock Music has many genres including classic rock. Rock can be in general anyone that gets together and makes a song whether it light, heavy, and anything in between. What makes classic rock different is one thing longevity through the decades. When a classic rock song is made it bypasses all time it sounds good at any time any year and pleases a wide Audience. For example Def Leppards song Bringing on the Heartache sung by them is a classic rock song. Where as Maria Cary singing the same song is not a classic rock song.
Hotel California by the Eagles is a good, slow rock song. Another slow classic rock song is Stairway to Heaven by Led Zeppelin. One by U2
One of the best I believe is House of the Rising Sun by the Animals, or Stairway to Heaven by Led Zepplin
They are considered Classic Rock, Oldies, or Pop, depending on the song.
