disappointed with the answers here.
Heres the deal on all that, and we have a link some where here I will try and link you to that has a sample contract for leasing beats.
I believe you can apply online for ASCAP or BMI, those companies ensure that you get paid whenever a song you have registered with them plays. (generally)
I recommend ASCAP as BMI isnt very customer service friendly unless you are selling million I guess. I have yet to recieve any help from them even though I have emailed them over the years.
lol, soon as I figure out how to get away from them I am.
Copyrighting your beats is pretty simple , you basically fill out the copyright forms and send in a cd with your beats on them. Last I heard it would cost about $45 per cd. I say that because you can copyright songs individually but it would be $45 each, a good idea is to put as many songs as you can on a cd and name the entire batch something like "Yung Boss Beats Vol1" and then attach a list of the names of the beats to the form. It goes to the spot up in DC and takes around 6 months to get a response from them.
Make sure that all the beats on the cd you send in are just you, if you have say a bass player on 3 out of ten songs you are sending in and you want to say something like " all songs done by me except songs 3,5,9 on the list in which it was me and bassplayer X" they are gonna reject that and ask that you send in seperate forms for those songs.
I will go and try and find that lease contract for you but it may be under the part where you have to have a producer page for it, dont know if Fade will let me repost it.
EDIT:
I found it, it is under the producer page section once you sign up for your own page.
PM'd you the info.
Now go buy the page. lol
