Soundful uses artificial intelligence to write and record music. Having experimented with it, I'm confident you could generate an album of more than acceptable tracks in two days and download the stems for around USD25 each. Import these to your DAW, record your vocal or solo instrument tracks and you're done. https://soundful.com/
Soundful has limitations: BPM (at least for some genres) only goes as high as 122, and requesting a minor scale is sometimes ignored.
