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.
This is nitpicking, but actually most ways to play a sound files in Pd are not totally gapless, unless the file lengths are exactly a multiple of 64 samples. This is the case with [readsf~ ], but also with [tabplay~]. Both start only on block boundaries. The only way (I currently can think of) to play absolutely gaplessly is to use [vline]/[tabread~ ] construct.

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
