I did some experimenting with a shell script that might help. I’m no expert at this, so take that into account. First, I used two .m3u playlists for mp3 files, but this will work with .wav files too. I copied the contents of both playlists into a text editor (Kate) and saved it as a file named combined.m3u. This preserves the proper play order. To get the following shell script to “see” the very last file in the playlist, I had to add a “newline” (hit the Enter key) before saving it. I created a subdirectory named CombinedAlbums to copy the renamed files to. So, the file structure for this was:
BillBruford/Feels_Good_to_Me
BillBruford/One_of_a_Kind
CombinedAlbums
The first two directories were ripped from CDs using Grip, and contain only mp3 files. Be sure that’s all there is in the directories (or only .wav files).
Next, I created this shell script, saved it in the same directory as the above 3 directories, and made it executable:
#!/bin/sh
tracknum=1
exec<combined.m3u
while read line
do
cp $line CombinedAlbums/track$tracknum-${line##*/}
tracknum=$((tracknum+1))
done
In the CombinedAlbums directory, it makes copies of the files with track numbers prepended:
track1-Beelzebub_Instrumental.mp3
track2-Back_to_the_Beginning.mp3
track3-Seems_Like_a_Lifetime_Ago_Part_1.mp3
track4-Seems_Like_a_Lifetime_Ago_Part_2.mp3
track5-Sample_and_Hold_Instrumental.mp3
track6-Feels_Good_to_Me_Instrumental.mp3
track7-Either_End_of_August_Instrumental.mp3
track8-If_You_Cant_Stand_the_Heat_Instrumental.mp3
track9-Springtime_in_Siberia_Instrumental.mp3
track10-Adios_a_la_Pasada_Goodbye_to_the_Past.mp3
track11-Hells_Bells.mp3
track12-One_of_a_Kind_Pt_1.mp3
track13-One_of_a_Kind_Pt_2.mp3
track14-Travels_With_Myself__And_Someone_Else.mp3
track15-Fainting_in_Coils.mp3
track16-Five_G.mp3
track17-The_Abingdon_Chasp.mp3
track18-Forever_Until_Sunday.mp3
track19-The_Sahara_of_Snow_Pt_1.mp3
track20-The_Sahara_of_Snow_Pt_2.mp3
Of course, you’ll first have to have the playlists to do this, but Audacious can export them. I hadn’t thought about it until now, but Audacious can make one playlist for all the songs, so that will elimated having to paste two or more playlists into one bigger one, saving a little bit of work.
I couldn’t find any application to do what you want, so hopefully this method won’t be a huge pain in the ***.
