Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Do they have to be the same bitrate or both be constant/variable bit rate?

Ya it should work

What about the id3 tag? Won't combined.mp3 just get the id3 tag from 2.mp3?

Comment by andrew112358 265 weeks and 6 days ago

The id3 tag could be anywhere, depending on the version. http://www.id3.org/FAQ so the tag and song durations that your player reads won't be updated for newly-larger file, but hopefully a good player will just keep playing the extra audio frames that come along.
