Bandwidth is... the width of the lanes a certain bit of the information superhighway has versus how wide the band's bus is. It's about whether the traffic (information) can get where it's going reliably and easily, or if there's a jam someplace.   It's more often a concern of end-users, as in "I'd really like to download the 1 million garbanzo-bytes of Tyler Quandeaux's new CD "Smell My Pieds, American Persons!" but I'm on a dialup and don't have enough bandwidth. See, Ty's got a really wide band (on the bus), and on my exit off the information superhighway,the snails have to walk (or whatever it is snails do) single file.

It can be a concern of the Server Dude though. As in "Everybody seems to want to download all the tracks on Ty Quandeaux's CD. Now, I've got a big honkin' on ramp with room for 10 of Ty's band busses to leave at the same time, but that 11th means the MIDI motorscooters are screwed and will have to wait.

If Max has a big enough server, it won't be a big deal to put a couple of MBs worth of one MP3 up for everybody here. Max may have a big enough server - I don't know, but bandwith is the connection people use to get to the server and the connection the server uses to get to the rest of the internet.   

It would be up to Max to say if he has the bandwidth to handle it. I mostly don't have the bandwidth to download MP3s. I believe long ago Max said he wanted to put MP3s up here, but for some reason, I detect just the slightest bit of sarcasm in "I'll get right on that."

An MP3 would be great on a person's profile. MP3s of DT songs would be great, but would be a pretty big project. Mudcat has always been more about the music than the musicians, and it's just barely about the music at all currently. Promotion of artists is best done at sites developed specifically for that purpose or on an artist's own page.
