Hi all,
TL;DR. Looking for help finding song Specific Backing tracks for Real Band. I know some can be purchased where would I look for that?

For those that want more context. My Dad and I had a band that we used Real Band to accompany us while we both played guitar and sang. He was very well versed in using BIAB and Realband having started using the program back around 2005(ish), He made many backing track to original songs as well as covers of popular songs. Our collection of songs quickly grew as well as his skill in creating more accurate backing tracks. I know later on he started importing custom instruments to get a specific melody or part. I also know he began to purchase and import complete tracks of songs to be more accurate and match the originals exactly. He Suddenly passed away from a heart attack in 2020.

I have not done much with music and the software since, but I am looking to get back into it. Now that I want to expand my repertoire, I'm a little lost on where to start. I do know the process he seemed to follow ( verbally) but am looking for any tips, or pointers on what to do or if I'm missing something.

I believe his process was, Import into BIAB, Setup chord chart (manually or auto populate then fine tune), Convert anything to real tracks(drums, bass,etc). Once track was made he we send to REALBAND where he could adjust and control each track separately. To perform we would make a jukebox file and use that for our live shows.
I'm also wondering if a person has to do the labor intensive way of making each backing track manually or where you would look for premade song specific backing tracks. I'm sure they exist, but how would you import them into RealBand. I know that on some tracks my dad had bought there is nothing but a wave file playing under the tracks tab, but we do have an actual chord chart laid out that looks the same as other tracks he made manually.

I'm sorry for the long post and thank you for any help or guidance you can provide.
