I want to offer a BIG +1 for a re-rip feature. I've been on the JRiver freight train since MC17. Before then, an iTunes user. Many of my CD rips are from the olden iTunes days. I would love to re-rip them using the MUCH BETTER JRiver ripper, but it's way too much of a hassle to reconstruct the metadata.
Anyway, since CD's have become so inexpensive (at least, in my case, a Classical Box buyer) an inordinate amount of my time is spent inputting data for CD's that should have metadata in a database JRiver accesses. Many are there, but too many are rife with mistakes; and others that you would think would have metadata are non-existent. I do my part inputting and correcting and uploading. So, another BIG +1 for improved access to metadata. I could reclaim a lot of time in my life with just these two improvements.
To be fair, JRiver has been a huge boon to my music listening. Considering what we all have invested in equipment and music, I, for one, appreciate Media Center, and everyone on the other side of the software for everything that you do; you all have added immeasurably to my listening pleasure and satisfaction. The time I spend with Rameau, Mozart, Beethoven, Wagner and Haydn (to name a few) and their champions Bernstein and Karajan, Paillard and Pinnock, Gardiner and Christie are made so much more rewarding and so much closer to perfection for what you do.
Thank You!
PS A/B comparison help sounds cool, too.
