Here are some of my favourite songs from You Tube. First a heavily edited Suppers Ready
Groove Armada: Inside my Mind
One of the most brilliant covers ever, at something over six minutes Walk on By
The wonderful Salva Mea at ten and a half minutes.
Another Brown Paper Bag Another Birthday (remix) Another Tijuana Lady

I could go on and on and on.

Modern tastes? Well I don't know any music lover today (whatever the genre) that thinks a song shouldn't be longer than three minutes. It was perhaps the default back in 1960 when a three minute song was necessary to get airplay - but back in 1965 a folk singer called Bob Dylan broke that three minute mould with 'Like a Rolling Stone'.
