I usually turn on AnimeNFO radio with WMP. For some reason anime and videogame music help me to concentrate :)

yeah, music+coding works pretty good IME.

less certain though, is recorded convention panels + coding, but this is still better than TV+coding, where TV tends to try to demand too much visual attention, which when coding is more needed to devote to coding. with convention panels, one can mostly leave it in the background until something interesting is said, or something comes up on screen which actually needs attention (vs just someone standing there talking about stuff).

multiple things involving natural-language will clash though, as my ability to fully mentally deal with natural language requires a lot of mental resources, though at a more basic level it is possible to listen to and keep track of several ongoing conversations at once (just not have focus on all of them at once), though noise-level and similar are fairly relevant for this.

luckily, natural language and coding are pretty much independent though, as code is mostly visual information, and most code-related thoughts tend to be fairly mechanistic, allowing for a little higher mental throughput.

like, I see some code and it seems to be processed "all at once", rather than sequentially (like natural language), and similar seems to also apply with things like looking at ASCII-text data files and often hex-dumps (though, this may involve more mental work if decoding the files' data from its hex dump).

however, I am usually unable to actually remember most of this...

like, my ability to actually remember information is on-par with my ability to type it out, which is at least a little faster than my ability to process or compose natural-language text (actually pretty slow). then again, some people have claimed that me typing stuff sounds like rapidly hammering the keyboard as well. but, OTOH, it still manages to take a long time to read, think-about, and respond to things.

back to the power of music in all this:

I think it helps in the sense that it can help focus things and provide a sense of energy and motivation.

though, this likely depends a lot of the type of person and musical style though.

or such...

This is all you need:

That is very beautiful.

I like this:

In fact I find most of Bluetech's music to be meditative when coding to it.

This one was the first one I heard when forced to learn the Java language at University :)

My computer can't handle Eclipse + YouTube/iTunes at the same time, so when I do listen to music it is pretty jittery.

I have been listening to YMO Solid State Survivor over and over. It gets me into a kind of "epic" coding mode where I start typing really fast.
