Try checking out IMSLP, which has untold tons of full-length audio tracks from commercial recordings accessible to paying subscribers for the annual subscription fee of just USD$28.00 (alternatively, $3 for a month) - alongside various other benefits not available to non-subscribers. Recordings of a given work by different artists (in numerous cases, 60 or more) are presented, some newly emerged, others renowned, and others vintage. Non subscribers can browse all its commercial recordings' covers but no more.
Tracks, where offered, are presented on pages concerning individual works. To access a particular work, you have various alternatives, presented on the main page (
https://imslp.org/wiki/Main_Page) starting from the horizontal navigation menu, that will take you to alphabetically ordered index pages leading to more specific levels and eventually to the work of interest.
For pages covering a work, which typically present one or more downloadable scores but may or may not present commercial recordings, navigate from "Scores > Composers"
For pages that include commercial recordings, navigate from "Recordings > Commercial Recordings"
For pages presenting recordings by a particular artist but not necessarily commercial ones, navigate from "Recordings > Performer name"
However you access a given work-page it incorporates the same overall content, but on landing conveniently displays it in a layout suited to the option you chose to navigate to it.
Alternatively IMSLP provides advanced search querying and various other flexible schemes for narrowing/ filtering its body of work-pages down to categories of your own specifying.
Truly outstanding value for money, IMO. For anyone aspiring to train as a pro record reviewer or music critic IMSLP would be the ideal boot-camp.
