I'm not a big fan of Psalms since there's a lot of wrath and vengeance. I do however like #100, and verses 1 -7 of #95, and other bits and pieces.
#95
1 O come, let us sing to the LORD; let us make a joyful noise to the rock of our salvation!
2 Let us come into his presence with thanksgiving; let us make a joyful noise to him with songs of praise!
3 For the LORD is a great God, and a great King above all gods.
4 In his hand are the depths of the earth; the heights of the mountains are his also.
5 The sea is his, for he made it; for his hands formed the dry land.
6 O come, let us worship and bow down, let us kneel before the LORD, our Maker!
7 For he is our God, and we are the people of his pasture, and the sheep of his hand. O that today you would hearken to his voice!
