The first hint was a morse code that contained these coordinates:
92.811631, 3.097632
If we decode them with Rot5 which also accepts numbers

It gives you: 47.366186,8.542187
Google maps: https://www.google.com/maps/@47.366186,8.542187,18z

You said that you are looking for only small letters

So limmatschiff was the password and unlocked the second hint:
AHukwv_VX9A

Which is the link in youtube of the song:

And if it goes anyfurther your +1 in the subject is very intriguing this could mean the first minute

If you google it the first story that pops up is the lost girl that became a princess
