I d/l'ed this app, and I am very happy with it's ability to *manually* send the occasional iTunes track out as Twitter message.
BUG: If the Title or Artist contains an "&", the app stops the message right there.
E.g. if one tries to send the following song,
Silver & Gold (When I Get Like This) by The Detroit Cobras, Twiiteromatic simply sends "Silver" as the song info.
The developer is very hard to reach, no feedback links available from his blogger sites used as their main site.
Please consider fixing this bug, otherwise I think the app is solid, fun, and worth the install.
