Just throwing this in here for comparison purposes:
My 133MHz slug has a 21MB songs.db file, with 14038 songs. My SB M1001 plays the entire library with no problems.
I’ve been expecting the SB to fall over ever since I passed 10,000 songs, but it just keeps going.
I guess you have many, many more tracks than I do if you’ve hit 100MB on your songs.db, but would you care to put a figure on it?
Just out of curiosity.
