haha I completely enjoyed this! I hate it when my iPod randomly freezes, it's so aggravating. I liked the imagery of the man sitting next to you, I think every one who loves music has had those angry glares due to blaring music. I agree that music takes the listener into a completely different world. It helps me to concentrate and to think about the day and my actions. Very nicely written.
Hope this boosted your desire to get back into your writing. I don'd really have an ipod but i do get it when the music stops. Especially when you wanna hear music and it's not there with you. Yea, i got that problem when i don't have any cd's with me ( i'm more of a discman person).
My only suggestion for you to be looking at is to work on your structure. You don't want to make your pieces flat. you can have amazing ideas but if you don't know how to make it attractive, those idea would not be as stricking as it should be. You can take something as simple as an ipod and turn the writing into something no one could imagine an ipod can do. Just think about that. Hope tha was helpful.
