Psalm 65 is another great song of praise to the One, True, Most High, Living, Almighty God of the Bible! Look first at verses 1-2:
1 To You belongs silence (the submissive wonder of reverence which bursts forth into praise) and praise is due and fitting to You, O God, in Zion; and to You shall the vow be performed. 2 O You Who hear prayer, to You shall all flesh come.
Praise is DUE to Him! Because He IS, because of WHO He is, and because of all that He has done! Look at James 1:17:
17 Every good gift and every perfect (free, large, full) gift is from above; it comes down from the Father of all [that gives] light, in [the shining of] Whom there can be no variation [rising or setting] or shadow cast by His turning [as in an eclipse].
EVERYTHING good in our lives should immediately cause praise and thanksgiving to rise up in us and be freely expressed! For more of the "why", let's look at Psalm 65:5-13:
5 By fearful and glorious things [that terrify the wicked but make the godly sing praises] do You answer us in righteousness (rightness and justice), O God of our salvation, You Who are the confidence and hope of all the ends of the earth and of those far off on the seas; 6 Who by [Your] might have founded the mountains, being girded with power, 7 Who still the roaring of the seas, the roaring of their waves, and the tumult of the peoples, 8 So that those who dwell in earth’s farthest parts are afraid of [nature’s] signs of Your presence. You make the places where morning and evening have birth to shout for joy. 9 You visit the earth and saturate it with water; You greatly enrich it; the river of God is full of water; You provide them with grain when You have so prepared the earth. 10 You water the field’s furrows abundantly, You settle the ridges of it; You make the soil soft with showers, blessing the sprouting of its vegetation. 11 You crown the year with Your bounty and goodness, and the tracks of Your [chariot wheels] drip with fatness. 12 The [luxuriant] pastures in the uncultivated country drip [with moisture], and the hills gird themselves with joy. 13 The meadows are clothed with flocks, the valleys also are covered with grain; they shout for joy and sing together.
He is GOD and HE is GOOD! Thank Him, praise Him, worship Him and then be sure to tell everyone you know about your wonderful and glorious LORD! Here is Hillsong United with "You Crown The Earth":
