Hey man I just read what you had posted on here. The main thing which of course I am sure you have is your copywrite. Did you send it to the library of congress or what is a poor mans copywrite?
If you have the copywrite and the paperwork showing that SAID company got X amount of songs from SAID writer then you should be able to take it to any court system in the United States and have them forced to respond to your request.
It should not cost you an arm and a leg to do this either. You can represent yourself as long as YOU have the proper paperwork showing they have your material and they are using it without paying you your royalties.
As is in most cases individuals who are in promarily the songwriting buisness they normally have an entertainment lawyer or at least a leagle aid that can help them in times of chrisis such as this.
I dont' know if you have representation or not but it is not a bad idea to find one and have them review your case. You do not have to have them represent you if you do not want them to. I think it's just a civil case nothing more. Most of those you can just be yoru own rep.
If you do not have all of the paperwork for when they purchased or well aquired the songs then hopefully you have the copywrite information. The copywrite is the most important information you can have. That will almost automatically guarantee you success in finding this silver fox in the snow.
It happens alot dear friend. There was a young girl on TNN a LONG time ago she had 20 #1 songs in the country billboards but she recieved no compensation for them. She did not know the process in which to get paid for the material so she relied on handshakes and words.
It would be great if people had that much Integrity to just use a word and a hand shake to prove they are honest people but sadly in this day and age the mighty dollar causes there integrity to dwindle with each cent they earn.
Also you may want to get into contact with the Manafement of the Artists tha thave used your material. They will have copies of the paperwork as well seeing that there performer is going to have had a contract that states that he is only the performer in the material and not the SONGWRITER.
Check with everyone that has had dealings with your material. If what you say is true and I do give you the benefit of the doubt then somewhere within all of the Artists and the company there should be paperwork that states that YOU are the SONGWRITER/ARTIST or PUBLISHER of said songs.
I know this is alot lol. I am sorry but I am rabbid about the music industry and music in general. I hate seeing good people get stepped on like this. It's bad enough that record companies are able to sign artists as a work for hire and not let them keep there material it's even worse when they have a WELL to continually get material from and they steal from it.
I am sorry for what has happened to you my friend I know that you are not hurting because you have other labels that are kind to you but you should definatley track this bastards down and give them what for.
Take it easy man and keep posting in here and let us know how it goes.
