Songbird killed my BASH script

I used to play music in the terminal. Why is this? iTunes didn't "really" support flac, and it makes an utter mess of my otherwise neatly organized collection. And, until very recently, Songbird failed to play certain mp3s for seemingly no good reason (silly encoding issues). Besides, I enjoy being able to rock right off of the prompt. But no more.

Just as I finished neatly merging a few scripts I had been using all this time, I found the aforementioned encoding issue, unsucking Songbird in what appears to be a fairly permanent way. *sigh* I'm just not elitist or bullheaded enough (most of the time) to cling to the terminal when better options exist.

Nevertheless, if you wish to play a mixture of formats over SSH, this may just be what you're looking for.
