There are two ways to move a track to another station:
1. Hover over the album art on the Now Playing page, click on the arrow that appears and select Move track to another station.
2. Click on the album art in upper right hand corner of the page and select Move track to another station.
Select the station that you think the track is a better fit for from your station list. Then click Add.
When you do this the track will get a Thumbs down in the current station and a Thumbs up in the station you moved it to.
