1.) get a mic headset for about $15 or so. this is the best way to go. the sound for what you pay can't be beat with an equal value hand held mic.
2.) get a program to record your vocals. most on the net use cool edit pro. acid pro works as well.
3.) sign up for soundclick first. then upload your tracks to your account. it isn't hard to figure out by yourself.....
4.)
www.soundclick.com/beatsbydren all on the site that are downloadable are free to use. i have beats all over my computer if you wish to purchase one for very cheap prices. (under $100)
5.) the best program out there to make beats with that is obtainable for "free' is fruity loops. get FL studio if possibe. you will need to download drum kits and other wav files to add to your sound library because fruity loops sounds suck. they are ok for techno shit but that's about it.
