Yeah wav is good quality. That’s what I would upload to Wavlake. If there’s a good solution where I can easily post albums with album arts and the genre I would like to try

Give podhome.fm a shot. I think they have a free month trial.

WAV is also huge. At least use a lossless codec like FLAC. That will cut the size in half. WAV will rape people's data plans, and most users won't notice the difference in quality. A high bitrate mp3 or AAC will be enough for 95% of users, and use 20% of the bandwidth. Most music services serve multiple bitrate streams, so users can select the tradeoff they want, bandwidth vs quality.
