Code to be Cracked

Hi, when I was younger I made a set of songs that were put in a playlist with a code for the name. Turns out the code was so good I can't even decipher it now.

.---- • ----. • ---.. • .---- • ----. • ....- •

I'm pretty sure it's morse code, it's definitely Sherlock Holmes related, and I used multiple different codes to keep this message hidden.

I thought this might be fun and save me ripping my hair out trying to figure this out. Thanks, any help appreciated!
