mp_suggest is a simple little organizational tool for MP3 collections. I wrote it a few years ago to help me organize my own collection, and when the Hy Programming Language came out, I decided it was time for a minor exercise. Rewriting mp_suggest in Hy was a perfect opportunity.

mp_suggest does not alter your MP3 files; instead, it prints to stdout a simple Bash script that invokes the command-line program id3v2; you can capture that script and run it by hand, or pipe the output of mp_suggest through sed to make changes on the fly, or just run the output straight into Bash with a unix pipe.

Writing mp_suggest was an interesting exercise in returning to Lisp after all these years. I find that I really enjoyed it (although, honestly, Hy's debugging facilities leave a lot to be desired). The style used inside mp_suggest is most definitely not Lispy; looking through it, with its persistent use of cheap anonymous functions and closures and its function-level metaprogramming, I guess the best language I could compare it to is Coffeescript. I like Coffeescript a lot, but I don't get many opportunities to use it professionally, but the sensibilities of Coffeescript (especially Reginald Braithwaite's Ristrettology and his other books on functional programming) heavily influenced the design decisions I made in mp_suggest.
