I was told that content posted to myspace become’s theirs, but I never verified it for myself. Turns out its true. From their TOS:
By displaying or publishing (“posting”) any Content, messages, text, files, images, photos, video, sounds, profiles, works of authorship, or any other materials (collectively, “Content”) on or through the Services, you hereby grant to MySpace.com, a non-exclusive, fully-paid and royalty-free, worldwide license (with the right to sublicense through unlimited levels of sublicensees) to use, copy, modify, adapt, translate, publicly perform, publicly display, store, reproduce, transmit, and distribute such Content on and through the Services. This license will terminate at the time you remove such Content from the Services. You represent and warrant that: (i) you own the Content posted by you on or through the Services or otherwise have the right to grant the license set forth in this section, and (ii) the posting of your Content on or through the Services does not violate the privacy rights, publicity rights, copyrights, contract rights or any other rights of any person. You agree to pay for all royalties, fees, and any other monies owing any person by reason of any Content posted by you to or through the Services.
The scary part: with the right to sublicense through unlimited levels of sublicensees
The reassuring part: This license will terminate at the time you remove such Content from the Services.
My two cents.
