I've seen pricing on serious bandwidth -- it's just too expensive. Example: REALLY good pricing on 50mb/s (20mb/s commit) is somewhere around $1600/mo. The 20mb/s commit means your average bandwidth for the month doesn't go over 20mb/s -- they usually drop the highest and lowest couple days or the like to calculate their average. Bump it to, say, 150mb/s with a 50mb/s commit and you're up to $2200/mo. The only other number I remember off the top of my head was for 10gb/s was well, well into six figures per month.
None of that's crazy if you need it, but it's going to hurt if you don't have a really good chunk of start-up capital to keep you going until you've set up whatever hosting/reselling you're hoping falls into place.
Anyway, point being, it ain't gonna work if this music project is having trouble with $500/mo. bandwidth bills.
