V1. A conversation usually made on social networking or chat sites through the sharing of links to songs. The rules are that the songs apply to the conversation through either the lyrics or title, and the poster must specify.
V2. In another subtler version, the songvo is made through setting a profile song and changing as the situation/convo progresses.
