Some band sites have free mp3s (Coheed and Cambria for one) so that may be an easier option than some others (seeing as how it might have alot more bandwidth than some of the mp3 download/warez crap). Also, as Morganlefay stated, internet radio stations are becoming alot more popular and there are ALOT of them now.. so it would be easy to find the kind of music you like easily and have alot of variety without waiting for downloads.


Another (simple) option would be to get flash memory cards, cd's, dvd's, or whatever your favorite media may be and download some MP3s at home, load em onto the media, and take them to work and listen to them. (Flash memory is becoming alot cheaper, so you could probably get a 1 GB USB key for 40-60$ US and as you probably know.. you can fit ALOT of MP3s on a 1 GB drive, or whatever else you want to add to it).


Just my thoughts.
