Let me have a shot at this. I actually used a lot of these services to date, emusic for 2 years, rhapsody, musicmatch mx, etc.
I think there needs to be a distinction between the riaa albums and the independent label albums and how they should be handled. I usually want to have full albums of the albums such as the ones in emusic, but probably get one song from jay-z or 50 cent, couple songs from eminem.
Also, I don't know why but I couldn't fnd groups such as Sonata Arctica, Kamelot, Rhapsody, Luca Turilli, etc. in these online services. So, a service that is more complete would win for me.
OK.
- First distinction needs to be between rhapsody kind of streaming and itunes kind of song downloads. I like rhapsody but why would I buy an album if I can stream it at high quality whenever I want. I won't buy albums from them if they only offer same quality downloads. If they offer a lot more, I would buy from them. Let me talk about a lot more below..
- First of all, I need either full or 30 second high quality streaming of the songs for previewing purposes. More than availability, easy accessibility is important for me. Itunes is doing a good job at this. But where it fails is, I need to click each song one by one to preview each of them. I want to be able to preview an album, as if it is a playlist, even loop so that I can listen to them over and over before I decide I want to buy the album.
- It is inportant that I have access to information such as the most popular albums of an artist, most popular songs in an album. AMG website accessed by MC has this information.
Good genre categorisation (Rhapsody is doing a good job). Also current most popular song listings in each genre, essentials for this genre, year by year top songs, etc. Again easy accessibility is important.
- Music files (hopefully mp3's) needs to have embedded full CD art, images, full lyrics (time syncronized?) and maybe extras. I should feel that I am getting more than what I would get in a real CD. These extras can be sort of DRM'ed, so that they can't be shared or copied. But if I move from one computer to another, I should be able to download these extras to my new computer from internet or the jukebox should do it.
- I need to know that I can get the lossless versions of the songs I bought. Bandwidth is expensive so maybe this can be a physical shipment, songs burnt to a DVD or CDs in a lossless format (and maybe with Apple style DRM if they must). Lossless format shipments can cause extra say, 10c per song, plus media, plus handling and shipment. But I need to know I have the option anytime I want.
- No DRM. Don't shoot yourselves in the foot. A better solution would be a per user-based digital watermarking. Which would mean, if you share your songs on kazaa, they can be tracked to you. It would be enough to scare people off even if it won't work 100% of the time.
- For non-mainstream emusic style groups, I need per album pricing 2$ or maybe 3$ per album is fine. Here I am in music discovery mode almost all the time. No DRM, why would they need it anyway. And since they are not too expansive nobody would bother stealing them. High quality VBR MP3 is a must. Mp3 is important for portability. No 128 bit mp3's. It is ok for classical music or new age, but it is terrible for punk, rock, heavy metal songs... For punk, 256 would be the minimum CBR.
- For popular, big label albums, a per song and per album combination pricing is ok. Again the ability to get lossless versions is important for me.
