my list of songs that either need more, or are long and good as they are:
Floyd - Shine On You Crazy Diamond (Part I)
Floyd - Marooned
CCR - Who'll Stop the Rain (**** you Fogerty, you needed to make songs over four minutes, not just one version of "Heard it through the Grapevine" //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif )
CCR - Lodi (same thing applies...)
Dylan - Desolation Row (eleven minutes long with no repeating chorus - and still could use more verses!)
Dylan - Lily, Rosemary and the Jack of Hearts (almost nine minutes, no wasted lyrics)
Dire Straits - Tunnel of Love (eigh minutes long, Knopfler should have spent an extra two minutes on the guitar & piano flourish at the end and it still would have worked)
The Byrds - Wasn't Born to Follow (you don't write a song with lyrics like this and only have it be two minutes! Roger McGuinn, you fool!)
The Doors - Light My Fire (little over seven minutes, and they really got the solo parts right.)
Allman Bros - Jessica (seven and a half minutes, works perfectly at that length)
there are sooo many more.
