Best '80s/'90s pop

Start collecting 80s pop/rock hit compilation CDs and chose from there. Or download mp3s.

Or if you have internet access and a means of burning your own CDs or ripping to disk, tune in any popular 80's oriented station and start recording/ripping.

If you have a Jack FM brand radio station in your area, those are another good source of lots of good 80's material. Their web sites usually have playlists and links to download the tunes as desired.

The thing is that the most popular bands of any time only produce a small % of the great tunes. To get a good representation, you need to sample a lot of music. That's where internet or over the air radio stations come in, particularly ones with good web sites that help you find out more about what's playing and what to buy.

Yeah, getting a DJ that has the tunes you want is probably most practical solution unless you really want to invest the time needed to pull everything together and make it work without a hitch.

BTW, the OHM Walshes are awesome party speakers if you choose to apply them towards that, although most people will probably be satisfied with the equipment that a hired DJ would bring to the table.
