I'm always talking about what the RIAA will and will not let us do. I found a copy of the highlights of their rules and regulations and thought I'd post it here.
All of what we do is monitored and reported on a monthly basis, so we have to be careful not to violate any of these rules or we could lose our ability to broadcast legally.
#1
In any three-hour period, you should not intentionally program more than three songs (and not more than two songs in a row) from the same recording; you should not intentionally program more than four songs (and not more than three songs in a row) from the same recording artist or anthology/box set.
#2
Archived programs (those that, when accessed, always start in the same place and play in the same order) should be at least five hours long, and should not be available for more than two weeks at a time.
#3
Continuous "looped" programs (those that always perform in the same order, but are accessed in a continuous play stream) should be at least three hours long.
#4
Rebroadcasts of programs can be performed at scheduled times three times in a two-week period (for programs of less than one hour) and four times (for programs of an hour or more).
#5
Do not publish advance program guides or use other means to pre-announce when particular sound recordings will be played. However, a webcaster may name one or two artists to illustrate the type of music on a particular channel; and, DJ "teaser" announcement using artists' names are permitted, but only those that do not specify the time a song will be played.
#6
Use only sound recordings that are authorized for performance in the United States (e.g.: do not play bootleg recordings).
#7
Provide some means for the end user to identify the song, artist and album title of the recording as it is being played.
#8
Lastly, the DMCA also requires that you accommodate technological copyright protection measures or pass through any identification, which may be included in the song recording itself, as long as it does not impose substantial costs or burdens on the webcaster. Also, do not deploy or support technological means to evade these requirements; and, do not explicitly encourage home taping.
