That is because your songs are not indexed correctly.
All of my songs were indexed when thy were flac files. My Accord handled the metadata with no issues. But the accord’s stereo took 3 seconds to start the next song.
I used JRiver’s Media Center to convert those flac files to wav files. That fixed the 3 second delay in starting the next song. But the metadata got tossed.
Note that I am playing all of the songs from a USB flash drive. There is no connection to a smart phone or any on-line database to retrieve metadata.
As flac files, the metadata was part of each file, and my Accord read and displayed that metadata, including showing cover art. I was able to search and filter by that metadata. But once converted to wav files, all of that was lost. But it remedied the annoying 3 second delay between songs.
Mazda at 15 GB takes about a minute or so to load on start-up.
I have approximately 200 GB of wav files on my USB flash drive.
I can start playing music from my USB flash drive in approximately 30 seconds. However, the first time that I plugged it in, it took a while to read through all of the files (for what, I do not know). But as long as I leave that flash drive connected, it does not perform / repeat that lengthy process.
