Venue downloads seem stuck? Switch to WIFI if on a cellular network or vise versa. Quit the app and relaunch it.
Check to make sure you have at least 500mb to 1GB of available space on your device in Settings. This is the recommended available space suggested for optimal performance with all apps. It is especially recommended for the iPhone 4S and iPod Touch (5th gen.). This can help to prevent LiveTunes and other apps from crashing. It can also help your songs load faster in the Player and improve audio playback performance as well.
