If AccuRadio plays just fine for awhile but eventually stops playing new songs, it may be gradually reducing the available memory in your browser tab.
Another issue some users experience is that clicking on a channel only shows the message "Music will resume shortly", but music never begins to play. This is usually caused by your computer having some temporary difficulty connecting to AccuRadio's servers.
The following steps should help solve either one of these problems.
Most often closing and re-launching the browser window or app should fix the problem. You can do this without closing the browser window on a desktop or laptop by pressing Shift+Refresh. In Windows, you can also press Ctrl+Shift+R. On a Mac you can press Cmd+Shift+R. (This keyboard shortcut doesn't work in Safari.)
For a longer-term solution, you may want to clear your browser's cache every so often. To do this in Windows, press Ctrl + Shift + Delete, and select which items you'd like to clear from the menu that appears. On a Mac, press Cmd + Shift + Delete. You can find more detailed instructions for how to do so by searching the web. Here's a good one we found:
