I'd like to point out that this is a good point. Mp3s and audio CD will have their own pros and cons.
For mp3s, a CD will be able to store much more songs (but in this case, only 1.5 times the equivalent capacity of a an audio CD). mp3s are also easier to send over the net to Levan through e-mail for their compact size.
For audio CD, the final product will be much more presentable. Mp3s in this case, can be seen as a tad too casual for mass distribution. I may give previewers an impression that local music is "cheap" or "no quality" cause they're distributed as mp3s. It maybe a hard to upload 40 MB of a song to Levan through e-mail... Imagine Levan's e-mail flooded by 2 GB plus of songs!
What I can advice for the next volume, if there is, is to ask people to send their demos through e-mail in mp3 format. After a selection of 18 or so songs, ask these bands to send in the raw non-lossy formats of their song though a 3rd party site such as yousendit to prevent e-mail clog-ups. With these wave files, produce normal audio CD which would be much more presentable to readers of LIME mag.
Either this, or stay the same for consistency sake or if there is drastic cost differences in producing a full CD and a 1/10 CD (for 30 mp3s)
