<human>: Give me a shortened version of the text

I'm one of those lucky few who has a job where we're allowed to listen to our iPods all day at work. Unfortunately, this meant that I had to expand my previously tiny music library so I wouldn't get sick of hearing the same songs over and over again.

I expanded by music library to about 3000 songs, and begun a personal project where I trim it down, only putting the stuff I really like on my iPod and organizing it in a way that works for me.

To begin, I created three playlists (Rap, Rock, Dance) to generally group the songs I wanted to sync so that I could switch between genres quickly and manage the files easier.

Next, I started rating all songs using the following system:

1 - Remove from syncing playlist

2 - Trim either the beginning or end of this song

3 - On the fence about keeping or removing

4 - Keep on playlist

5 - Always keep on playlist and automatically added to 5 Star Playlist

These simple steps have helped a TON, but I feel like there's got to be other simple ways to organize songs. Once everything is rated, I was thinking about grouping all the genres and making smart playlists that way (IE, group all rock as either Hard Rock or Soft Rock, all rap as Hardcore Rap or just Rap, just to differentiate within genre a bit).
<bot>: I've been messing with the ratings and smart playlists to manage my music a lot more efficiently. Anyone have any tips who's taken on a similar project?
