I did a quick impressionistic/non-scientific review of the MBLR (MusicBee LyricsReloaded source group) and (SLLP) (Slonopot Lyrics Plugins) last night to check on where we are right now in terms of viability with existing scripts. It was by no means "exhaustive" or "extensive," and was done on radio streams only using artist and track title metadata. I excluded Viasona and Versos Perfectos from testing as I have no familiarity with predominantly Spanish language and Catalan popular music/streaming radio.
I was looking at results that at a quick check seemed accurate (i.e. found the song in question). Except where commented I used the Slonopot-modified mb_LyricsReloaded.dll for MBLR, which was created in an attempt to deal with the captcha and changed source structures on some of the websites (Metal Archives, Genius) without causing problems on others.
My overall impression was how WELL the MBLR sources and search scripts still held up, even odd-ball ones like the built-in and MBLR versions of "Lyrics.ovh," Pesni Guru, etc. Since the latter normally end up placed on the bottom of my search list, searching either ended with a hit well before reaching them, or none at all, giving the impression that "those sites stink", etc. For the test I used "Search Next Provider" to cycle through all hits for every song that was being played. I tried to use a variety of genre stations like the Soma FM selection for Pop/Folk/New Wave and many Radio Caprice sources for Goth/Metal/Esoteric.
My limited results showed that with MBLR and the search source scripts available both built-in and from the downloadable "providers" YML folder, only six never produced a single hit: Google, Lyrics, Lyricsify, Metrolyrics, Cuspajz, and the Genius "scrapers." Hats off to Mayibongwe!
The "alarming" zero-results from the Genius scrapers (which by the way included test YMLs from Slonopot that worked for a while then quit even with the mod DLL) was made not-noticeable for anyone who had the Beenius plugin from the SLLP group also in use. This single plugin was "visually" (I told you it was unscientific!) the source of the most hits of any in the whole test and across a wide range of genres. The other two in the SLLP group, Museexmatch and LCRCLIBee, showed up almost as frequently.
Some surprises included the frequency of results from "Bing', which I think like non-captcha Metal Archives was assisted through use of the modified mb_LyricsReloaded.DLL file.
For the future I would recommend Mayibongwe and Slonopot decide on a specific path for the DLL that includes the helpful mods and use that now in every distribution As there are now two versions of the same file floating around: the newest 1.27 from the normal download which is 233,472 bytes and the modified version of the original 1.26 which is 234,496 bytes. Also, expanding the availability of API-based searchers (Bandcamp, etc.).
