I think part of the problem is there are extreem left-wing songs, so you think the concervatives must have extreem songs too. Only problem is extreem is a bit contray to definition.
Exactly what conservative stands for is up for debate. For that matter so is liberalism. If you find two people who agree with each other on everything you will have shown me at least one fool, perhaps two. With that in mind I'll try to add a few things: conservatives believe that you can and should make yourself better. They belive that only you are standing in the way of your ability to afford a million dollar house. (most also don't want a million dollor house, and would agree that a large house doens't bring happiness) Therefore conservatives belive that you should use your abilities to make your life as good as it can be. concervatives belive that liberals stand for doing whatever you want, and if your too lazy to work you should be paid to stay in bed all day. Note that concervatives are not against helping those who are unable to work, they just belive that there are very few such people. Concervatives want a goverment for protection byond thier ability to protect themselves. They see liberals as wanting protection from things they could very well deal with themselves.
The above is how I see concervatives in the US, as others have pointed out in other countries they stand for very different things. Also note the "they see" up there. reality is in the eye of the beholder.
As for why there are no songs, most concervatives belive in doing something not singing about it. In their eyes, a liberal would write a song about needing more blood doners (a netural topic I hope) while they accually sit in that chair and take the needle every 3 months. Of course the liberal will take the needle too, but liberals would write a song about it.
You decide how much of the above is true.
