I'm being asked to sign a perpetual non-exclusive agreement by a library...does this mean they have it for ever and I couldn't remove the song ever?
@shadowfax Yes, that is
exactly what they mean
To be fair, music libraries invest in building up bodies or work and circulating hard drives etc. to music supervisors
The last thing they want is to do all of this work and then have a song "pull out" so the perpetual license is an easy way to administer this
If they are offering a non-exclusive agreement you can still use it for other purposes (but check the splits)
You really need to almost get rid of any emotional attachment to songs when writing for libraries - write it, send it, sign it, and forget it - and then get on with writing the next batch!!!
It sounds really callous but that is how most treat it - and the ones that do really well are the ones that think like this but still produce tracks that sound like they have their heart & soul in it
