An idea for the growing cover/arranger market: 1-Stop Page or Service to check a cover song can be licensed and distributed by Soundrop.
A page or Soundra-incorporated question hub to check EasySongLicensing (or other relevant databases) with significant confidence before Soundrop Artists produce and/or release cover music to answer the common question of "Is this song eligible for licensing, through a released CD in the U.S" or similar qualifications.
The anime and video game music scene is heavily reliant on asking Soundrop staff or each other for hearsay or less-organized data to ensure covers are licensed, and a center to answer this question could help centralize the info and encourage licensing through Soundrop itself.
