The iRp app song search (different from forum’s google search) searches your library (or playlist) by “keyword” (or letters).
That’s actually far more useful than “ First letter / few letters to the song”.
Say you were searching (by initial song letters) for A-Train.
You won’t find it…the title is
Take the A-Train.
Green Dolphin Street? Nope, it’s
On Green Dolphin Street.
With “keyword” search, just choose whatever you think is the rarest/most unusual word anywhere in the title and start typing.
Is the title “Say It’s Only A Paper Moon”, “ It’s Only A Paper Moon”, “ Only A Paper Moon” or just “Paper Moon”? Each miles apart in your library. No matter… Just start typing p-a-p…. There it is.
Tons of songs have “Moon” in the title.
Try searching “Love”……. Yikes!
I stopped scrolling ages ago.
