Should I change the name?

I once said that when it comes to titling an abstract photograph, you can call it anything you want, because it's abstract - who's going to argue with your title? I titled one of my photos something like Ice Cream Dripping on a Sidewalk on a Hot Summer Afternoon - just because I could.

I figure the same reasoning could apply to a song that is instrumental - right? I've been debating whether I should rename The Great Escape when I post the instrumental version. In the lyrical version of my song, Great Escape refers to an escape from a dreary life running in the rat race where it's a drag just getting out of bed, to a life of passion and adventure with every day bringing so many possibilities.

However, I wonder if the title is a bit of a cliche. This title is shared by the classic 1963 movie (which I haven't seen yet) about an escape from a German POW camp. The band Marillion also did a song with the same name on their 1994 CD Brave. Is this title already overused?

Alternate titles I've considered for the instrumental version are Evolution and Metamorph. The way the three sections of the song build towards the climactic ending make me think of the metamorphosis from larva to pupa to butterfly.

Probably I'm second guessing myself and should just stick with my original title though.
