歌曲欣赏
《平凡之路》The Road to Ordinary / Be Ordinary
For those who wander on the road
Where do you go
via via ~~
For those too proud who walk alone
Why are you standing far from home
And when the storms rage on the sea
What do you need
via via~~
Alone in silent reverie
Are you still listening to me
I’ve climbed the mountains I’ve crossed the sea
Moved through crowds on busy streets
Once I had it all in my hands
Until it fell like grains of sand
Made my ways across the high ways and byways alone
But the road that’s ordinary is the only way home
When you lost inside a dream
What it will be
via via~~
Will it be better off this way
Or is it just another day
Once I burnt it all to the ground
Walked away and left this town
Clawed my way back up through the dark
Tried to fight and missed my mark
Made my way across the sorrow and laughter alone
But the road that’s ordinary is the only way home
I’ve crossed the sea
Moved through crowds on busy streets
Once I had it all in my hands
Until it fell like grains of sand
Made my ways across the high ways and byways alone
But the road that’s ordinary is the only way home
The road that’s ordinary is the only way home
