there's an interesting tool that game audio folks use that does some clever prestidigitation when encoding an MP3 and generates a gapless version. it runs on a PC, but can run under Wine pretty easily. requires old fashioned WAV files for input. here's the link. the page also has a lot of detailed information on why MP3s have this issue and how the tools solves this problem:
Well, if you require WAV for input you might as well convert to OGG which AFAICT doesn't suffer from this problem.

Pd will play all files gapless, according to their file length. The 'gap' problem mostly refers to the MP3 format, which encodes the audio in fixed frame length. So if your song doesn't fit neatly into a multiple of the fixed frame length, you get a gap, i.e. the leftover part of the last frame is filled with silence. That's a problem with the MP3 format that basically all other file formats don't have.

Yes I do have the ability to change the playlist file to a text file and alter it how it looks. The thing I'm looking for is an example of gapless playing. I couldn't find one doing google search.
Thanks

Greetings All
I have a playlist file (songs.pls) that I would like to play gapless (without the 1 second pause between tracks) can puredata due this if so is there and example?
It sounds doable to me. I'd do it with [textfile] reading your playlist which passes each line (after some message mangling) to a [readsf~]. My only concern is the chosen file format '.pls'. Pd (natively) is pretty bad in string parsing. If you could use your own format it would make things a lot easier. I don't know if you have any constraints there.
The simplest format of such a text file might be as an example:
filename1.wav filename2.wav whateverfile.wav
